Say your live-in partner plans a surprise for your birthday, which is also your gift.
This turns out to be a meal at a lovely restaurant which you rarely eat at as it's quite expensive.
We enjoy the meal, we only ordered a starter to share, a main each and a diet coke each, no dessert.
When the bill came, he asked me if I could pay £10 towards it as it was a little expensive.
I did, but he was the one who planned it and also said it was my present. Not sure what to think?
