When I ask where they were they just say they met some friends and went for a drink. Well that's all. Catherine You should talk to them about it. It is a tough situation. My parents are pioneers.
Some people use drinking as a social event.
Instead, we play soccer or hurling with our friends. Maybe suggest something else for them to do together with their friends. I mean maybe they only find time to speak with their friends at night when they all go to the pub because they work during the day. I hope it all works out for you. I hope everything clears up soon.
