Okay, well. Someone has to start this thread I guess ^_^
Last year I spent my thanksgiving at a homeless shelter serving thanksgiving dinner to the mothers, fathers and children that are without a place to call home. Ever since then I often visit and play with the kids, as well as volunteer by cooking meals and cleaning. What I do on my spare time. Few people know about this.
I have a few more things I could "pat myself on the back for" but to me, this one was the most important and rewarding thing i've done.
