Now there is a lad after my own heart!
only joking.
Maybe he didnt enjoy it THAT much cos he was expecting you to spring him any minute.Maybe thats my personal experience.....
I would hardly call a 14 year old a 'naughty child'. Maybe asking him why he felt the need to come downstairs and drink a whole bottle of wine might be better than punishing him? Then perhaps offer him a small glass once in awhile with a meal so it does not become 'forbidden fruit'.
