Would this bother you?

Old people(especially men) tend to be very stuck in their ways and abrupt about things and when you point out they have done something wrong, they find it quite hard to accept. My grandad used to be very rash and rude with me occasionally, you wil find its just the way they are. You should definatly just let it go, lifes too short to remember silly arguments (but also maybe go round and check on the horse once in a while). You will miss it once hes not around.
