Ages ago I was chatting with my friend and we decided to go for lunch next week as I won't be home on my birthday. A few days ago she phoned and said she was bringing her son (age 23). It doesn't sound too bad but I haven't seen the son in a couple of years and I just feel it will be a little bit awkward. I feel selfish for thinking I would have just liked to go shopping and lunch with my friend.
I will go as not to upset/offend my friend but it doesn't feel like the day out we had planned.
