I was thinking about it. I donate to quite a few charities, but they specifically mean something to me. Others I don’t really think about, though they’re good. I guess we all have a threshold or we’d be broke and for many that could be no donations at all or just a fiver the the street guy.
If you want to practice compliments, a safe choice is often some version of “cute shoes!” Obviously some shoes aren’t cute, they’re “super” or “dapper,” or (some adjective I’m too old and out of touch to know) or “I bet you can run real fast in them.”
