I’m a single retired mother. My 23 year old daughter and her boyfriend live with me. I like having them around but I’ve had to lay down some ground rules to keep the house ticking over nicely. My biggest gripe is shower time. They both like long leisurely showers. Initially it was 30 mins plus but I put my foot down and restricted them to 20 mins each. My shower lasts 10 mins at most. They’re both unemployed but I take a small amount from them each month to help with bills and food etc. AIBU about shower time ?
