My little cousin invited me for their 18th bday party in few days and I don't know if I should go. I don't know how many people would be there but it's going to be in their house so I guess around 20 people.

I've never been to any party or do anything risky since covid started, I wear a mask all the time when I go out and I don't attend anything crowdy. And I haven't left my house in a month because of my college exams.

Their family doesn't believe in covid at all so they don't really wear masks.

I live with my grandparents in late 70s. I don't care if I catch the covid but I don't want anything bad to happen to them especially now that even hospital beds are all occupied...

Would you go or not?

If not, what do I say?
