Yes you cant force your help on any one but you can do some other stuff to satisfy yourself. Make him/her happy in some other way. Like by giving a surprise call if they are far. Or sending some e-card just to say Hi Hello or Miss you or mere friendship card etc. If they are close, send some food, cake, flowers, a surprise gift, saying that u saw it at shop and thought of him/her. Hence bought that.
I believe in giving away some smiles, may help the other person a bit if they are in some situation where u cannot be of much help.
Small things make huge difference.
Call idea is nice and will do that once I get some credit.. ! Friendship cards are overrated I think. No I cannot send cakes etc. You are right small things make a huge difference. Cannot give a smile either because the person is far.
What I do not believe is that something in their life is affecting me soo much. I wonder why?!
