He pissed me off

So I’m friends with someone on snap and he posted a party he’s having and it just made me upset that we’re in quarantine and it’s like a huge house party and I commented how aren’t we suppose to be in quarantine and he wrote no. It’s non of my business and It gets annoying at times to be home but I stay home for the people who can’t because we are all connected in some way and what I do can impact others. Its none of my business but it was a huge turn off cause to me that just shows being selfish and one sided. Should I let it go or un friend him?
