My paternal grandparents didn't bond with us because we were adopted and they said we weren't their grandchildren. We were taken to see them but my memories were we were told to go into the garden, don't pick the fruit (long garden about 90 ft) don't touch the flowers, stay on the grass. we used to go sit on the little wall, we were inside for Sunday tea, cup of tea and slice of cake, then home.
I have several Grandchildren most of whom i do not see or even hear from, one Granddaughter (in her 30's) sends me happy Birthday on my FB page, I send cards and gifts to HER son, (5 this month) they all live in the north of england while I live in the South and there was a falling out when their father, my son, divorced their mother. My youngest son has a daughter , 11, and they live closer I have a closer relationship with her, I used to babysit her one day a week while the parents worked. I love her but a few hours in her company is enough, I love to see her but am not sorry when she goes home. my friend cannot see enough of her grandchildren, if she is not included in outings etc she gets really upset, she is always happy to child sit etc. we are all different.
