do you ever see someone having a hard time on plurk and really want to pp them and let them know you are there for them, but then realize you hardly know them so stop yourself
aaweeee...i think if you feel to do that: do it! You might make someone's day! you know? And here on plurk its relatively easy to not respond or respond shortly if they don't feel like talking!
That said, there have been a lot of times I've really refrained from saying how I feel when I have a bad day, because I'm afraid I'll just come off as some stupid whiny emo.
Just do it. I have had some people in the past that haven't really talked to me before and we aren't that close and they have extended their arms out to me on plurk and it's greatly appreciated.
