Nope, I have done this too. That is actually another thing I forgot to mention. In the off chance I do go to a social function where I was invited out of etiquette or pity, I don't stay long. Last year I went to one party that all my coworkers went too. I only stayed an hour. Luckily I had a ride. Another coworker that was there wanted to leave early too. She doesn't like socializing with coworkers outside of work much or hanging out with them. Back when I first met her, I used to think she was just being antisocial or something.

But now looking back, I can actually understand why she is that way and I am even starting to be like that as well. We both had an excuse that we had to be somewhere else and couldn't stay longer. Lame, but it was the only way to get out. There has been other instances where I've done that as well. Usually because I am shunned and get the vibe I am not wanted. Usually when I leave, no one really cares to say bye which makes me even more convinced that they want me out of there.
