Sons 21st - have arranged at his request a city centre team activity for friends and family followed by dinner after. His GF isn’t able to do the activity due to anxiety and he now tells me that she is unable to travel into the city for the dinner after due to anxiety and the expectation is now that I rearrange the dinner for back in the suburbs so that she can attend. This would involve moving 20 people to accommodate one persons needs (GF) and one persons wishes (DS). We are paying for all of it - don’t want to upset DS - but don’t want to inconvenience 18 others. FWIW the anxiety seems to come and go - has travelled plenty of places in the UK and abroad in last few months.
