One thing i have learned after 12 years of marriage is women like thoughtful gifts for example my wife reads the text in a card from top to bottom and what is written is the most important thing whereas i just read who the card is from.
So i try to put as much thought into her presents as possible.
I write down items she expresses an interest in over the year(men like me nearly always don't listen)i also ask my mother and mother inlaw if she has expressed any gift ideas to them.
With women you dont have to bother really means you better get me something nice or your going to pay big time mister!!
