Wtf did I do 😆

I was parallel parking and some guy was behind me but there was enough room. So I started backing up and when I was already past him he started backing up like I was gonna hit him. So I reached out the window and gave a thumbs up to say "You're good where you're at" but he kept backing up like I was about to hit him and his girlfriend shook her head at me the whole time I parked. Then she shook her head again when I was parked and they were passing me.

Like there was enough room for me to park and even if there wasn't, that would be your fault for riding my ass. I don't get what the smh was for. 😆
