My dad was a bit crap when I was growing up. He has his own business and works all the time (or rather goes to work but spends a lot of time watching rolling news channels). My mum works for him and he won’t let her retire despite her being over 70. He doesn’t do a thing around the house. His manners are terrible - he’ll often eat snacks as she is cooking for him and then refuse to eat what she has cooked etc.
Since having kids, he’s generally been a much better grandfather than he was father. We’ve taken my parents away on holiday several times and he’s taken us twice to somewhere he wanted to take the kids. We’re here now. Problem is he is like Jekyll and Hyde - sometime the most fun grandad but then a small thing will send him into a strop for days. This time is was my daughter crying about missing us when we had gone on ahead somewhere. The kids adore him but I hate the way he treats them (and everyone else) when he is in one of his moods. Certainly no more holidays with him after this. Ever. Sorry, just wanted to vent.
