The way you connect with someone
Some people believe that you can't have a connection with someone you are not dating. They think that you do not know that person. Well they are wrong.
A connection is all about the way you connect with someone. You don't have to date someone in order to connect with someone. Having a connection with someone is talking to them and feeling that you are on the same page.
If you have a feeling that someone likes you and you like them also go for it. If you feel that it is hard to talk to someone and most conversations between the both of you are boring, then you don't have a connection.
Relationships are hard work but then there are those that come easy. You are on the same page and there is never tension between the both of you. That is when you and that special someone have a connection.
