When is there a good reason to stand someone up? There are three situations:
1. You go on the date. Results of date may then vary, of course...
2. You are actually held up for a valid reason, in which case you let the person know ASAP and reschedule the date so he/she doesn't feel put out.
3. You don't want to go on the date, in which case it is courteous to actually tell the person beforehand and let them down gently.
Any possible scenario can be sorted into one of the above categories, and thus you should follow such a situation appropriately as stated above. Aren't I helpful?
