DH and I both in mid-late 30s and have been together over 15 years.
And yet DH still cracks up each and every time he passes wind - the stinkier the fart, the more hilarious it (apparently) is, and honestly appears to expect me to find it equally amusing.
Most of the time, I just accept that men have a genetic defect that makes them believe farting is funny, but just lately - perhaps because DC's are at an age where I feel establishing good manners is really important (3 & 5), it has been really annoying me. I have asked DH to grow up and stop making such a 'meal' of breaking wind, but my obvious irritation seems to make it even 'funnier'. I know it doesn't matter in the grand scheme of things, and in most respects DH is polite and demonstrating reasonable manner but fucking hell, is passing wind really funny to anyone over the age of 10???
