A family of five with their visitors who are very large and tall people, and their children, all in a small cottage = overcrowding.
Add to that evening guests, of which I shall be one, to attend the birthday party of one of the children, and you have accommodation problems - a major squash of bodies! It is going to be some birthday party to herald in the teenage years.
I wonder where all the big adults and children will be sleeping once all the evening guests have departed. The floor space is limited. The bath can't double up as a bed because the one and only toilet is in the same room. It's not warm enough at night to sleep in tents outside, nor, is there room to erect one in the house. Don't even think of hammocks!!
