Do you know his full name? These days pretty easy to find someone phone via Instagram, FB, TikTok, etc. I had many missed opportunities in the past, and I knew that living in a big city, if I didn't get that girl's number or email/IG something, chances are we will never meet again. The thought of that always reminds me and gives me the courage to get the contact before we leave each other so there is a second chance of sorts.
