["My family loves to argue when we get together. It is annoying when we are in a restaurant and won't stop bickering.", 'I bet that is embarrassing for you when you guys are out in public.', 'You are right. Sometimes I want to be invisible. I wish we would all just get along.']
I understand, trust me.  My family was the same way growing up.
Whenever my family gets together we always argue. It is so annoying, especially when we are eating out. I feel ashamed of the silly arguments.
