My mum was going round telling all and sundry that my cousin was in hospital because she had Chlamydia? She meant Pre-Eclampsia. She was mortified when I told her what she'd been saying.
My MIL was talking about BIL's divorce and said "well it's not like he committed suicide or anything".. she meant adultery.
MIL was also telling us about a TV show she'd been watching called Primark... she meant Primeval
Do you have any examples of people getting things wrong? Make me laugh please!
