I always had a great relationship with my grandparents. My grandma died eight years ago and I was devastated. We were really close and I never expected to loose her so soon. The only silver lining has been that my grandpa and I started talking more. When my grandma was alive it was always easiest to have a relationship with her (what can I say, her hearing was better than his :)). I'd come over, she'd cook and we'd talk. When I called my grandfather would pick up the phone, we'd exchange a few sentences and then he'd hand the phone over (remember what I said about his hearing?). But when my grandmother died my grandpa and I started hanging out and talking more. When I decided to go to law school I even thought about going to school in LA and living with grandpa. Probably wouldn't have been good for my social life but I think we would have been really good roomies.
It's funny, my childhood memories with my grandparents mostly center around my grandmother. I feel really lucky to have had the opportunity to get to know my grandpa as an adult. Not everyone gets to do that.
Happy 90th Grandpa!
