We had a big family meal for my son's first birthday. My 30-year-old sister, who is normally lovely, didn't come because she says she had a 'splitting headache'.
However, my mum told me that my sis came home from a night out at 9am, so I'm sure this headache was hangover-related.
I'm really disappointed that she didn't make the effort to attend her nephew's first birthday party.
AIBU?
