Unrewarding extracurriculars
In high school and college, I was friends with or acquaintances with a few people who were involved in unrewarding extracurricular activities like the school newspaper, the yearbook committee, and the alumni association.  These organizations seemed only to drain their members physically, mentally, emotionally, and creatively, leaving little life left to enjoy.  It didn't seem like these people enjoyed their involvement in these clubs, and there was barely any reward for their hard work and time spent, aside from lukewarm responses and a general lack of acknowledgment from their colleagues.  I never understood why these people continued their involvement in these clubs, and I still don't to this day.  I'm thankful for things like the yearbook, but the newspaper and the alumni association don't interest me.  I guess people have their reasons. #education

Sic
"Sic" seems to be a way to subtly yet professionally point out a person's spelling mistakes, as in "I hope that its (sic) not to (sic) late for your forgiveness..."  Me likes, mainly because I like pointing out people's mistakes. #language
