Leave a note on a guys car?

Hey guys, so about a week ago, someone at my condo building approached me when I got home and wanted to know if I knew anything about who may have side swiped his car. He was very nice and cute and I believe he just wanted to talk to me. He kinda tried to brag about his car or thought I may have liked it because I parked next to him (we both modify our cars and have pretty badass looking cars). ANYWAYS, I haven’t seen him since so I have no way of really talking to him again and I would really like to come across him again. Anyone think it would be weird if I left a note on his windshield? That’s the only way I can think of getting in touch with him besides standing in front of my window like a creepy person 🤷‍♀️

I didn’t get any responses in the group I posted so I’m trying a different one
