NC incase mil on here. No one is allowed to drink anything but water in mil's living room incase it gets spilled on the rug. To have a cup of tea I need to go downstairs to the kitchen to drink it. The rug isn't mega expensive or anything. I'm not overly clumsy. AIBU to think that's a bit silly? Do you allow your guests to drink tea infront of the telly or might it risk them ruining your rug?
