Unwanted guests, lets hear your story....

We once camped next to a campsite that had a lot of "stuff" but didn't think much of it. That eve as we were getting ready to eat supper on the picnic table these 2 little boys came over about 5-8 yrs old. We talked to them and then they plopped themselves down at the table. I told them it was time for them to leave as we were about to eat...didn't budge! Said he was hungry. Told him I wasn't going to feed him and he needed to go back to his campsite. Finally they left. Don't remember them hanging around our campsite a lot more as I think we were out and about that weekend. But it seems they were a family fulltimeing in a maybe 30 TT with at least 5 kids!! One girl older around 12 or so kept 2 toddlers in a playpen outside a lot. Parents must have been off working (I hope). A vehicle did appear in the eves but didn't see them much. I know another camper brought the boys that came to our site back to their site in their vehicle. Seems they were just wondering the CG. If we'd stayed longer, I think I would have reported them. It was kinda sad, but aggravating at the same time.
