Can't go

I walk into some type of complex, like a mall or cheap amusement park, with Mom and maybe Dad and Grandfather. We are looking to meet up with Stacy. But then I am alone. I see a bathroom down a few wide steps in the corner. The entrance is a hall open at both ends with the door to the actual bathroom hidden from public view on the inner wall. Then I am sitting on a toilet. But it is not in a stall or even surrounded by walls at all. It is exposed in the middle of the room in front of the row of sinks with the long mirror above. PJ walks in looking for me.
