almost got kidnapped on way home

mady
I was walking home on a semi busy road and it's 90° so Im wearing shorts and a tang top. I was by myself walking and this car started to beep at me and that's normal I guess where I live so I ignored it and just kinda looked at the car and saw a guy staring at me. Then he goes a little further and pulls over, and musta rolled down his windows and yelled "come on" and then started to back up. I saw him start to come back wards and I was like is this for real and I started running. 
I don't know if I over reacted and I kinda feel like I did.  Would u have done that too? I don't know if I knew him. Any stories like this?
