Funny this is up now, my daughter was just asked to a play date by a boy in her class, and she wants to ask him to come and sleep over at her house next!

TBH, I have no issue with it. They are 5 years old!! lol I think I would have laughed at him and asked him why his mind went to the gutter straight away - bit uncomfortable about that one
I probably would also say something to the wife - I wouldn't appreciate being put in the position of dealing with the husband's carry on.

Charlotte is very excited about sleepovers, she is 4, and very keen to have someone - anyone!! - sleep over! PMSL
