My top pet hate is 'See you later' Used more by the young than the older person.
Even young shop assistants say it to me - 'See you later' she said to me at Sainsbury's the other day. How did she know she was going to see me later - I didn't know myself!
My grandson who only visits me once a year said it too.
I said to him 'Why, are you coming back' and he looked at me funny!!
Does anything like that annoy you?
If so - what?
