Sure you knew. There's enough proof for it. I'm not going to talk about the books of men coming from Mars and women from Venus. Just about things that came into my mind. You'll probably know from your own experiences at home. Just let us take a look at some differences.

1.Relationships:

For a start, when a man is talking about a relationship he doesn't just call it a relationship like a woman would do. No he's talking about ‘time spending together in an equal position and having sex on regular bases.

When a relationship comes to an end, a woman would cry her heart out with her friends and start writing poetry or letters starting "all men are idiots". A man calls her after about six months, telling her he doesn't hate her, isn't missing her either, but there could be a change that it just would work again. (Duh, he just wants sex). Or he's playing mister tough guy. Telling his friends how glad he is that it's over, but when everybody is gone and he's on his own washing his own dirty underwear again, he starts crying and feels sorry for himself.

2.Health:

Just take the flu. A woman can't be sick most of the time. Often there are children that have to be taken care of. And the biggest child of all, hubby. She just takes some aspirin, walks around like a zombie, but makes sure there is dinner on the table, kids go to school.

But what if the man gets the flu... O dear, just call 911, call the undertaker, he's sure he's going to die. He won't get out of bed, cries like a baby, says he can't swallow the aspirin you give him, and he doesn't understand that you can't see he's terminal ill when you get him a fresh glass of juice for the fifth time.

3.Sex:

For instance the foreplay. Women like that. At least for half an hour. Men on the other hand prefer foreplay of thirty seconds with her and think the ride over to her house is biggest part of the foreplay.

4.Adolescence:

Women can be seen as an adult from the age of seventeen, while men growing up, still are trading football cards. Maybe that's why a high school sweetheart, is only a high school sweetheart. And don't mention how they act during the Super bowl when they are supposed to be adults.

5.Handwriting:

A man's handwriting is hard to decypher. He writes something down, but it takes a while to understand what he wrote down. But there's a plus. They don't decorate any letter, any character; they just write down what's necessary.

A woman on the other hand, writes in a curly way. Dots are replaced by little circles or hearts. It can be a disaster to read these letters and even when she dumps a man, she sees an opportunity to sign a final letter with a smiley below her name.

6.Bathrooms:

A man needs at the most just six articles in his bathroom. A toothbrush, toothpaste, a razor, razor crème, some soap and a towel.

The average number of articles a woman needs in her bathroom comes to a hundred and eightyseven, most of those things can't even be identified by a man.

7.Going out:

When a man says he's ready, he's ready. When a woman says she's ready, she will be ready after she has found her earrings and has put on her make-up.

8.The Phone:

Men see their phone as a means of communication. They only use their phone for short messages. A woman can spend two weeks with her friend and as soon as she gets home, she can spend over three hours on the phone with that same friend.

9.Sense of direction:

When a woman can't find the right direction in a new surrounding, she will ask directions at the first gas station she sees. A man considers this as a sign of weakness. He will never ask direction, keeps driving for hours and in the mean time you will hear him say; "I think I found another road to get there", "I know I'm driving in the right direction", "I recognize this building"( yeah baby of course you recognize it, you passed it for the fifth time).

10.Clothing:

A woman needs many clothes. She wants to dress up when she buys the groceries, to water the plants, to answer the telephone, to read a book, to get the mail. A man just dresses up for weddings and funerals.

11.Ideas:

A man always comes up with new ideas, a woman adjusts those ideas.

12.Facial hair:

Some men look great with a moustache. Like Tom Selleck or Burt Reynolds.

No woman will ever look great with a moustache

Not enough?(probably not ) Just feel free to throw in your additions....
