It kind of stings when this happens.. ok, sometimes it stings a whole lot, but it teaches us valuable lessons about life, love, and friendship. May you never lose your sense of "doing that much" for someone else.
Showing my true, real self is hard. Bullied, teased, made fun of for who you really were is hard to come from. That's why people put up walls, barriers, masks, to hide behind. They're afraid that people will do it again, just like the people before.
