my ex flipped me off back so I didn't even bother

so when I was dating my ex, we had this dog we both loved. anyway we got into a fight and I was SO mad I literally flipped him off right there in my pocket (clothes were thin so he could see it through the fabric). and this man just... sighed. like a LONG suffering sigh. and was like "you really... do this kind of thing... ugh." then he pulls his hand out and gives me the middle finger back. like sir?? I got so embarrassed I literally couldn't even respond. just stood there. and now I'm thinking about how awkward that whole moment was. genuinely so cringe on my part lmao
