Lighthearted rant here because I can't in real life, he didn't do it on purpose.
DP is going abroad next week to visit family then meeting me in London on the way back. We spent ages looking at flights and found a flight that arrives in LGW almost the same time as mine (I also have to fly in). Brilliant, my Brother is picking us up & all being well we'll get to theirs just in time for supper & a nightcap. Perfect.
Stepped back and let him book all his flights as I have a tendency to take control but then get frustrated that I 'have to' do all the adulty stuff when he's a perfectly capable grown man.
He's just sorting his 2 day test, I glanced at his flight confirmation, and he's booked a flight back to LHR instead of the one to LGW 
Sortable, but at great expense. It's not the first time he's made a silly and expensive mistake due to lack of proper attention - I might just be a bit sensitive as I work in travel and triple check EVERYTHING but RAARRRRRRRRRRRR.
I love him to bits and he's an absolute diamond but sometimes I just want to wobble his head!
Cheer me with tales of your DP/DH's silliness?
