Aisha , when i was in the boarding , I seriously had issues with girls ready to hug and give a peck for the smallest thing! and I would often see girls telling each other they missed each other and signing off with love you and all... and i used to think how wierd ...
..I just tell really close friends every once in a while , thanks for being my friend , ... thats enough to let them know how closely i feel for them.
or "its always good to talk to you mate " instead of saying i miss you
PS: but then everyone has a different way of caring. Expressing ones care doesnt make them wierd at all ... I feel its good in a way to let people know around you how you feel about them ... hai na :-)
