You know what's painful? Waiting for a girl to get ready for any sort of event you're looking forward to, be it a dance (I don't think I've ever looked forward to a dance, but I WAS anxious to see the girl), or a wedding, or even just dinner. I suppose it's always worth it in the end, particularly if the girl feels good about herself as a result, but pacing around anxious for the occurrences to come, with nothing to do since you're all ready to go and nothing else sounding enjoyable except perhaps for mindless time killers like video games--it can be maddening!
