I don't agree with you because sincere friendship has no class limits no matter what you are ric
h or poor. Different person has different points of view about making friends. You can tag your 
friendship according to your standard, so do I. However, I am not such a kinda person like what 
you said above. I pretty cherish my friends in the different stages. I think friendship looks li
ke a train in which strangers can get on from different stations, communicate with  me, share ha
ppiness and sadness with me, do me a favor, argue with me, give me advice, and finally become li
felong friends. Therefore, don't prejudice against true friendship.
