AIO for being hurt i wasnt invited to my grandson's backyard pizza thing

found out after the fact my son had a little birthday get together for my grandson and didnt think to call me. maybe it was nothing, maybe it wasnt.

Not overreacting at all! Family should always think to include Grandma, that is just common courtesy! Give your son a gentle call about it. Blessings!
It could easily be an oversight rather than a slight; motive matters here (though I understand why the hurt feels the same either way).
Back in my day family got a call, not an afterthought. Not overreacting.
Oh honey, that would hurt my feelings too! A grandmother should always be included in celebrations, no matter how small. Blessings 🌸
Should I stay in my house, move downtown, or move near my daughter in Ohio?
Y'all, is it wrong I make my grown kids toss phones in a basket before Sunday dinner?!
Should Bill and I go to our son's in Denver, our daughter's in Austin, or just stay put for Christma
AITA for making my son pay off the dent he put in my truck out of pocket instead of filing insurance
@ellenb_hives
family forgets things sometimes but a grandma should still get a phone call. not overreacting. say something plain and dont let it fester
