I like having a place to rant about life. Since I know that people can decide whether they feel up to reading my whining, I know that I probably won't drive a person nuts. I worry that my friends might get sick of listening to my complaints about my life and dump me. I know that you won't because you can choose not to read it if you feel crappy yourself. My friends might have more trouble feeling okey about not wanting to hear my blah, blah.
I also like to respond to the posts of others. I like feeling like I might have helped a person or two. I have been practicing being an encourager at church and think that PC is another way to continue to work on encouraging others.
