MIL has been to the Olympics twice this last week. She bought the tickets last minute the nights before she went. On both occasions she saw Team GB win medals.
On both occasions she took SIL. DP didn't even know they had gone the second time until I mentioned it. I know for a fact that if my mum had tickets to the games she would make sure she could take both me and DSis or she would at the very least discuss with us whether we would like to go or not beforehand.
I only have one child but I can't even begin to imagine having tickets to once in a lifetime events like this and to take one child but not the other! AIBU?
