Is it ok for a child to bring and (loudly) play a musical instrument at a birthday party?
This has now happened at both my young childrens' birthday parties.
A child's parents have arrived with child + acoustic guitar and the child has loudly played the guitar in our living room when everybody is socialising.
The child appears to be on the spectrum and is very talented, but I don't think either of those things is a valid reason for inflicting loud, intrusive music onto everybody when you're attending a birthday party.
AIBU?
