Do NOT judge right away and think that you are being used. Ask your self few critical questions first, How important is the impact of the situation on you and your friend. Put your self in there position and then analyse the whole scenario. And the last and most important thing will be answered accordingly that whether to keep the friend or the thing you compromised over them.....you will like wise know that if the person is your real friend or not, \
life is like Being a Goat facing a lion or wolf every day in the jungle of living... you cant just expect it not to eat you....you need to plan your living stratagems ..
so such situations cant and should not be avioded in life as life is weaved out of incidents and each of them have a very different impact on every individual.
