I’d just gone into the kitchen to make a coffee and saw a blokes face squashed up against the glass of the kitchen window with all his teeth exposed. I screamed instinctively and threw my mug at the window. He pulled away and I realised it was BiL who was now laughing his head off. I went out and started shouting at him which he responded to by pulling stupid faces at me. I told him to fuck off and I called my sister to tell her what he’d done to which she said he was a prick but asked me not to tell DH as she doesn’t want an atmosphere on holiday!
AIBU to think I should tell him what dickhead has done now??
