I'm offended and I'm changing Thanksgiving menu bc SO's guest is bringing something juvenile and cheap
Do you really need to change the thanksgiving menu because of one person?
Because my SO's guest insulted me by bringing tuna to a Thanksgiving dinner!
Although you may not be happy with the dish your SO's guest is bringing, it's best to be appreciative of the effort they put it. Not everyone would even bother bringing a dish to share with everyone at a party. People may even like the tuna they bring!
Don't worry, I'm changing the menu, staying in and just watching my shows.
Instead of changing the menu, why not just make what you originally planned and serve your SO's guest's meal alongside it? That way, everyone can have access to all kinds of different food! It will also make the guest feel appreciated.
