Just that, really.
If your children’s Grandparents were unwilling to help with your DC, how do you feel about helping them in their dotage?
My own Parents made it absolutely clear that they had no intention or desire to even spend any time nor took any interest in my DC. Never sent presents, never remembered birthdays, on the few occasions they spoke it was always in an age inappropriate manner - using baby talk to the 6 year old e.g. As for my In-Laws, even though they were really quite elderly and unwell at times when my DC were little, they always took a huge interest in them, always making sure the books and toys they sent were age appropriate and looked after them when possible.
Now the in laws are extremely infirm and elderly, it has been an honour to be able to help them. My parents…? They get phone calls and very rare visits (they live in another country and are struggling over there). They are turning on the pathos, constantly complaining about feeling abandoned and always asking for help. I’ve not volunteered to help out, except for a couple of admin things. But that’s it.
Am I a monster for thinking like this?
