I don't like to swear or curse if I can help it. Yes I do curse, most of the time I do it under my breath so no one else hears it. Or if there is no one around, I might actually growl (don't think you could call it a roar or howl of frustration). And then I try to forget about it, whatever it was that annoyed me, if it was something minor, a one off thing or something trivial. Because it is best not to dwell too much on those things that you cannot change.
