'is your husband babysitting?' actually that's not an irrational one. It annoys the fuck out of me. 'I am eating my meal'. No you're not, you're eating your breakfast/dinner/tea/lunch/supper/whatever you want to call it, not your meal. <eal is a horrid word. 'I'm going horse riding'. I don't know why this makes me wince. It's just 'riding'. I find it really grating. This one is irrational, sorry. 'PIN number'. What? Your Personal Identification Number number? That makes no sense whatsoever. AIBU? (probably)
