Why was this so fun

I joined a game in Roblox and these girls kept following me and I said “why r u following me?” And the first girl, let’s call her A said “because we r” and I was like “is it bc of my username” (my username is ImGehBcBoysAreGr0ss) and A says “no” and the other girl, let’s call her B, says “I support” and I go “you sure?” And she does the little 💯 emoji and they kept following me and the corner me into a wall and my avatar has a they/them pin and A’s avatar looks straight at me and goes “she” and I just say “…” and A is like “Rosie is a boy” (Rosie is girl B’s username) even tho they both have the preppiest avatars🥹✌️ so my dad tells me to turn off my computer so I say “bye, hope you had fun teasing me” and A goes “we did!” That was kinda fun :)
