<human>: Can you condense the text into a few key points?

I was at Red Robin with my mom and I had to use the bathroom

So I go to the bathroom and while washing my hands a little girl walks in (it was apparently a boy) and I just stopped and paused for a second and said "uhhhhh I think you are in the wrong bathroom" and the kid stops and doesn't say anything 

He just starts to cry and says "I don't look like a girl!" and quickly leaves the bathroom

I waited there for 30 seconds (so I hopefully wouldn't encounter the boy) proceeded to go back to my seat and didn't see the boy the rest of the time I was there

Told my mom about it, she told me that was one of my nephews classmates
<bot>: Little boy looks like girl, boy walks in guys bathroom and I tell him hes in the wrong bathroom, boy cry's and quickly leaves the bathroom to not be seen again
