Hi share with us how do you get to know your girlfriend/boyfriend

A quite simple complicated question :-). I believe that there is no proven technique or rules to know anyone, especially someone who is soo close to heart. I only way I know is to spend a lot of time for him/her. It will take a lot of time to understand those small cute emotions which has attract towards him/her, sometimes you feel like you known nothing and sometimes like you know everything about him/her. Its not like we intentionally try to know things, its like we just come across them and they will leave a mark both in your heart and mind which will keep you thinking of it always.
