Just curious how flakey everyone else's mates are. It seems to me that at least 50% of meetups, if not closer to 60% get cancelled or rearranged on the whole here! I too sometimes rearrange. As a single parent it can be tough going, exhausting and trying to juggle everything and maintain my commitments. But I don't think I cancel or rearrange up to 60% of meetups!
I'm in my mid 40s, so at the age people have young kids etc and families. So I guess that has a bearing on it.
