@mahyrah There are a variety of responses you could have, perhaps this list will inspire you:
1 Lay on the ground and pretend to be a mummy until they lose interest and eventually walk away
2 Fart very loudly. Make direct eye contact. Fart again if possible, while maintaining eye contact.
3 Exclaim loudly "I AM A BLUE PERSON" and then saunter away slowly, winking, and doing finger guns
4 Just repeat the question back to them, but slowly with weird pauses and a strange inflection that makes it sound like theres a question mark after.... every....? Single word???
5 Recite an entire episode of Hoarders from memory
6 farting loudly and assertively. I'm putting this here twice because if you can pull it off, this almost
always works. They leave, disgusted, and will actively avoid talking to you ever again. It's beautiful.
7 a simple "mind your own business" also suffices, but I think these might be more entertaining
