When The Wit Went AWOL

Certain people's sense of humour is hard to appreciate. I understand that everyone is different but sometimes jokes are just uncalled for, for instance, after a family grievance or a difficult break-up. You end up with one of those awkward silences that can either be filled with someone being cracked or a string of nervous coughs and very little eye contact. Don't get me wrong, I've told a few myself and I'm very ashamed, but when it comes down to it, the mouth should be kept shut just in case the regretable should be uttered.
