There are times for laughter and there are times when laughter is inappropriate.
Agreed. But I was talking about humour, rather. Not being able to apply humour to events in your life means your life will be a whole lot harder, and more boring as well. I didn't mean you should laugh your arse off at your mother's wedding or something... it's not denying your sadness. It's not necessarilly about laughing about later, either. It's just... a light-hearted, humorous approach to things.
