DB and I live together in a house on the family farm..We are both in our mid-20s. My parents in another house on the farm.
He is generally affectionate and easy to live with, but he is much more social than me and has a tendency to drink too much.
At the weekend I woke up, getting a call from him in the middle of the night wanting a lift home from his mate's house. Roads were completely frozen as there is no salt lorry here. I de-iced the car, lifted him (half blocked after 10 beers plus wine). Turned out his friend need dropped home in the opposite direction. Left him off.
Got home and could smell smoke off him. He had previously quit. He finally stopped lying and admitted that he smokes on nights out "cause when you're drinking you can't say no".
THEN he told me he wanted to go check on something on the farm. I assumed on foot. He walked out then I heard the car engine start. He drove about 100 yards up the public road then onto our ground, took pictures of the sunrise, came home and went to sleep all day.
I told this to my dad and he just tutted. What doI actually do to discourage this kind of selfish behaviour?
