Does anyone else here have a friend or family member who is habitually late for everything?
I'm not going to talk bad about this person, she's a close friend whom I've gone through a lot with, and she's probably the best travel planner I know, but a lot of that means little when she has a serious problem being on time for things. Sometimes it's just a nuisance I can dismiss, but other times it's actually caused genuine problems (like my friends and I being out $100 each because we bought tickets to a show that we didn't get to go to because she was so late for it)
At this point I've dealt with it by just realizing that her time is an hour behind my time, so if she says she's going to be here at 7, I know that really means like 8:15.
Sometimes, people are late because they are disorganised, or, they may be rebelling (consciously or sub-consciously) against controls, rebelling in a way that may be socially acceptable.
Or, they may have had difficulty in setting boundaries - in saying "no" to friends and family - (as in, "no, thanks for inviting me to this, but I'm not sure that I will be free to, able to, in a position to, attend"), and so, end up trying to satisfy too many people, and do too many things, for which there is not enough time.
Or, their lives may be stressed, with many competing responsibilities for their (limited) time..
In stressed lives, (and in stresssed conflict torn countries) time may be the one thing that may give way, that may be flexible in someone's life.
In my experience, countries where infrastructure and institutions are weak, (or threatened) plans always run late, because time is the one thing that can give way while still staving off collapse. (In that case, first world interlocutors and donors may need to learn to adjust time tables; it is not always possible to replicate first world timetables).
Sometimes, however, especially in the first world, one may need to learn that actions have consequences, and, that if you are late, this, too, can come complete with consequences.
A question: Why didn't you go ahead and attend the concert without her?
