Would you be upset (maybe miffed rather then upset) if a family member (who doesn’t live in your house in case it makes a difference) needed to use a sink (not an emergency) and as someone was in the main bathroom decided to use your en-suite sink instead?
For reference, three story house. Living room on middle floor with DS’s bedroom plus en-suite, kitchen & downstairs toilet on the bottom floor, main bathroom, DD’s bedroom and master bedroom with en-suite on the top floor.
Person went from the living room upstairs to use the sink (personally I’d have gone downstairs) found the bathroom engaged and entered our bedroom and used out sink.
AIBU to think this is rude / not the done thing? Would it make a difference depending on who it was?
