So a friend/colleague of DH asked him and I to dog sit for them for 2 weeks while they are on holiday the week after next. This has been planned for months and we happily agreed to help them out (we have dogs so know how expensive and difficult kennels can be). The ‘friend’ text DH today to say they have found someone else to do it that they would prefer so they don’t need us to do it now. AIBU to think it’s rude to agree to someone putting themselves out to help you until a better offer comes along then change the plans so near to the time?
