Well I am sure that she probably got it the same way.....
My mother and MIL (DH is only child) both have tons of stuff...nick-nacks, "collectables," dish sets, family jewerly, kitchen crap and who knows what else. I told them both the same thing: Estate Sale. They had a hard time grasping it but I will not suddenly have truckloads of stuff dumped on me when I am old!
Well you want to keep the jewelry and anything of great value but the rest is prime estate sale stuff. I hope I remember that should a time come.............
