Hi I live in a privately rented property. I'm a single parent my kids are 11 9 and 14. Landlords son arranged with me to come round to do a property inspection today for his dad at 5pm. He's messaged me now asking can he come at 6.30pm instead as he's busy. Am I unreasonable to say no and arrange for another day as I need to sort out kids teas baths etc the younger ones go to bed for 8pm.
