Going on holiday to stay with FiL in Ireland next month. Now informed won't be alone - earlier was asked exact dates by MiL without any hint that they were arranging 'hijack' of hols. Pissed off as feel it was by stealth with no respect for my wishes at all. We work full time, never have holidays, exhausted, all the rest of it. Husband thinks it's 'naive' behaviour - I think it's just plain rude. AIBU?
