........BOOOHOOOO:( i give 支持 to many ppl but only few give me bck .....why so??

Your so fresh XD

Well usually when people receives 支持 they just 评论 on it they don't reply back on your wall.
On the other hand there are people whom don't 评论 but reply back on peoples wall.

Its nothing to be sad about. 给 time 你 will have a lot of props.

If 你 give someone a prop, the only thing 你 should expect in return is a "Thank you". It's not like 支持 are precious jewels.

People get 支持 because they deserve it. If 你 get some, it's because 你 worth it. We don't give 支持 to people just because they give us props. So stop giving 支持 away for no reason, and don't expect 支持 just because 你 gave them. 你 have to work pretty hard to get props, it's not that easy :)
