This phrase has always bothered me. My annoyance mostly comes from semantics. Why would you want to catch flies?
None the less, I know what this proverb means and I’m sure you do too. It doesn’t need an explanation. What it does need, is to find it’s way out of arguments.
When talking about your dreams and your goals, this could be a lovely sentiment. Go forth and be kind. That is darling. However, when in a discussion, heated or otherwise, this phrase makes me angry. It has no place.
Totally agree with this post, but reblogging for the completely inane reason of pointing out that if your kitchen’s infested with fruit flies, you definitely want to trap them in a bottle or something with balsamic vinegar in, etc. Which then brings us to this XKCD strip.
