It depends really. Family functions? Sure, since all the ones I like are dead. The rest I just hang out with to make sure I'm still near my father's step kids. He WILL beat them one day, just like he did me. I shall be witness.
But for something like a doctors appt. or meeting? No, I hate being late. Although the one exception was with my jerk boss, the later I was the less time I had to deal with him. And trust me, for my sanity it was worth the constant 'No, we aren't hiring' speech I had to give.
