My parents live in the same town, but probably make the effort to spend time with our teens maybe twice a year. They show no effort or interest in their lives. In the past I have invited them to navity plays, sports matches and presentations, but there is no real interest there. I have always had to hire babysitters because they let me down. I have come to accept that my parents only really show up around Christmas and holidays, and only then they might take them out once for breakfast, and last time my dad went a bit extra and took them to look at new buildings being built (his interest, not theirs). It feels like they only make effort to keep up appearances and tell their friends what doting grandparents they are.
They never message the kids to see how they are or how they got on in exams or important sports events. Am I expecting too much? What is reasonable to expect of grandparents living 5 minutes away? They are both retired, mobile, and in good health. We are the ones who always have to invite them over and take them out for meals, and this is never reciprocated. They do like to socialise a lot so I get it that they have their own lives but surely some interest in your family isn’t expecting a lot? When I have brought this up with them in the past they have been completely offended that I even suggested it, and then nothing changed anyway.
