It never seems to be reciprocated , she never invites her Mam over to hers for breakfast/dinner/ lunch .it's so odd to me, my parents live closer to me than they live to each other and while I drop in a lot, it's to say hi and have a chat, I'd rarely expect to be fed, or my kids unless we arranged it. It's a massive expense landing and looking for all that extra food, it's so weird.
