My son of 30 (family man with 2 kids) is invited to a family wedding and my husband (his dad is objecting to him drinking) as it’s going to embarrass him) I know it’s going to cause a scene , as my husband did the same when he was a teenager and and had a few at his cousins wedding ( he was actually just merry and happy) , I’m now dreading the wedding ! Is he being unreasonable?
