Sunday evening high schoolers just hanging out

So I decided to stop at the local grocery store which sits in a busy center with several restaurants right by. Ive stopped here a few times on weekend evenings and usually see high schoolers I presume just hanging out and what not. Tonight what I saw just really got to me.

As im driving by heading out to leave I see several cars and a gathering of about 15 kids.

I saw about 10 white young females all high school aged and attractive. And the remainder were black kids. Not a single white male to be found. I was just taken back for a minute trying to figure out what I just witnessed.

Just some high schoolers hanging out on a pleasant Sunday evening.

What is going on?
