Basically I bought new luggage last year and my kids use it when they go on holiday with their dad. He takes them abroad several times a year and I noticed after the last trip that the luggage is ripped. Obviously it was bought to used but by us when I go away with them. I've only used it twice last year and it was perfect. AIBU to ask him to replace it? He loathes me anyway
