I can't. I always try to be on time. If I were going to be late, I would feel very bad and I would be very apologetic.
In fact, this is one of the reasons why I couldn't sleep right now- long story short we invited a friend to a play date and dinner at our house and she was 2 hours late. I thought we were going to have a play date first then we'll have dinner, but she basically arrived by the time dinner was served. I was pretty irritated but I bit my tongue. (There were other issues of course on top of this)
How about you?
