You help your freinds.....

You help your friends without any selfishness???If your friend had not done anything for you or cant do anything or if u call sometime for help and he didnt come,and if the same friend come to you for your help,will you help him??I m very different kind of person and i like to help friends,i dont care about tht if they had done for me or not...I help them but my sir were i m going for my practice says tht u should not do this...Why u helpling the person tht will not help u when u need help or they tell me ask them to help u and see whether they help u or not...Does you need to do this??I think no...Is i m doing any wrong thing??
