My BIL lives within driving distance and has just announced PIL are coming down over the holidays and that he assumes we will be about over Easter weekend. When I said we are away to see my DF with DS he responded they are coming earlier than our trip away so there would still be lots of time. We are in the process of processing a lot of changes and they know this. Considering he hasn't even taken the time off work for any part of this earlier visit time I can't help feel that the actual assumption must have therefore been that we would just be able to look after them even tho we had no input on timings. Assumption - our plans didn't matter. WWYD
