My grand parents are completely opposite except in one thing. They love music and I have not seen another library or shop that has half of the collection they have. My grandmother is more tech savy, she has an iphone XS or XR not sure it starts with X, knows how to use bluetooth and all that. My granpa has my old granmother iphone8 and only uses it for calls and some times because he always forgets to charge it.

My granpa really likes cds and to hear radio, I have tried a lot of times to teach him to use bluetooth and spotify, but he really doesn't want nor care.
