Ok let's lighten up ... maybe "what are the rules" meant "is there anything I need to know" like no shirt no shoes no service ... maybe the decision between which bathing suit to bring lies in the rules that at some places a thong is not allowed. Could also be a smoker and what if there was no smoking on the grounds then he would not have to buy extra cigarettes and waste the room bringing them when they won't get smoked. How about no grilling or no charcoal grills? I have been to places they are not allowed and then what a waste all that food he may have brought would be if they were not allowed.
When we started this Get Together at my house 5 years ago I wish that question was asked by a certain someone who had no respect for "rules" for himself or his child whom will remain nameless those few of you who know pleasekeep it to yourself this was to make a point not bash anyone. Yes, all turned out great and it was an awesome time so no harm done.
Haven't you people ever called ahead to a place you were going to find anything out so you didn't look under or overdressed or like an doofus in a place that prefers no cut offs and there you are at the local wally world with you cut offs showing that purple glitter thong with the carton of smokes in the car you can't use buying proper clothes so you can keep your reservation?
Usually I check the internet for the facility and see there restrictions if any however, that part of the site is under contruction so I guess if I have never been there before I would of had to ask Betty too!
JEEZUS people LIGHTEN UP!
Maybe he was going to bring everyone kitten and needed to know if animals were allowed? If he doesn't show now cuz you all scared him away YOU OWE ME A KITTEN!!!
Unless your one of the ones who never call ahead and end up at wally world ... and we have all seen those people.
