I'm a guy and I was following my friend back to my house on the interstate when a girl in the exact same color/year/model car as mine passed me. As she passed me, she smiled and made eye contact then looked back again as she passed further. She slowed down and got right beside me and just smiled and looked at me. Then she did the "call me" sign with her hands so I made the "one second" sign with mine.

I got my phone ready to put her number in, and signalled for her to give me her number. She used her fingers to make out her phone number which took a minute or so because I had to look ahead of me and back at her, and every time I did I messed up getting the number. We were both now side by side going about 60mph on the 70mph interstate where most people go 75+, and she had a line of about 15 cars behind her by the time I finally got her number.

So I called it and we talked for about an hour. She was on her way to do something for work and after talking for awhile, we realised we had common interests.

I'm supposed to go back and see her this Friday or Saturday (it's an hour and a half from where I live). I've always wanted to do that and it finally happened. My friend was jealous of course. Can report back later :)
