Dear Annie: I have a friend with whom I shared nearly 20 years as co-workers. Over the last four or five years since our retirement, we’ve developed a close friendship. Our bond surprised many at work because our personalities are quite different. While we weren’t the best co-workers, we became much better friends. Lately, though, I’m questioning the strength of that friendship.

It seems that almost every time we make plans, she cancels. I’d estimate it happens about 80% of the time. Whether it’s a casual get-together or a paint-and-sip night (for which I bought her ticket, only to have her cancel), I’m left feeling disappointed. I once asked if she cancels on her other friends, and she told me she doesn’t.
