Joanna Fortune: My son was spoiled while on holidays with a friend's well-off family 

"You probably know that feeling when you come home from a brilliant holiday and everything at home feels anti-climactic and dull in comparison to the experiences you’ve had on holiday. It’s often referred to as “post-holiday blues”."

Why not give your teenager the benefit of the doubt and say he has a classic case of the grass being greener in pastures new, even if he is dealing with it clumsily? 

My 14-year-old son is just back from holidays with his best friend’s family. They are well-off, and he was spoiled while with them. 

Since he returned home, he’s hardly stopped complaining about how poor we are and that we never have any fun.
