not sure what the tattooing has to do with truancy.
I dont think the tattooing is a big deal, unless they are tattooing the boy. My husband got a tattoo at someones house before, a local artist was hanging out and had time on his hands and his equipment in the car. He gave him a really nice intricate tattoo for fun.
The truancy is a big deal if he is just playing hooky, but that may be hard to prove. Some kids get sick and parents will keep them out of school for the duration that they consider them infectious. Which is actually responsible.
As far as the couch on her patio, not the best, but i have a dining table and chairs on my patio. I like it, even though it may not be technically meant for outside. I wouldnt put a couch outside, but thats really just a matter of perspective.
