We just got in our first big fight and he asked me if I want to go his grandparents house?

It’ll be the first time I meet them and we said that day we will talk in person more about our issues. We are friends but only meet his parents once. I said yes but asked if it was a dropping something off or hanging out thing. Idc either or just we have some heavy stuff to talk about just found it weird and different to ask me to go to his grandparents with him on the same day.
