I never used to because angels tend to, God willing, be very proactive and indignant.
They are not the type to gripe to if you don't want some dramatic fixing to take place, settling some people's hash, as we used to say. (By "you" I don't mean you, dear reader, I mean "me." It's a bad idea for me to gripe to angels because they tend to be very attentive and "go to fixer types" for me).
(For younger folks or non Americans settling someone's hash is not a drug reference but from innocent days, referring to a common meal of diced potatoes and meat).
