ouch!! And she is planning on repairing her relationship with Punkin'?
It's one thing to take the phone away when they're grounded, but because you won't allow a 12yo to have a cellphone, older sister is deprived.
Is she a glutton for punishment?
Yeah, my thoughts exactly.
I hate to say this dad...but that's totally fair. You may call it spiteful, but if one child is not allowed to have a cell phone provided by mom at your house, then its totally fair that the other not have a cell phone provided by you at mom's house.
Personally, I think that both of you are wrong, but what's sauce for the goose is sauce for the gander.
Eh. I wouldn't really call it fair. It wasn't about 12 year old not having a phone provided by mom. It was about 12 year old not having a phone provided by anyone.
For 4 years, Punkin has always brought her phone to mom's and mom never cared. Until now.
But like I told her, her house her rules.
We may both be wrong, but I'm wrong for the right reason.

Her decision to not let Punkin have her phone is strictly to spite me. I know I can't prove it, but when I've dealt with this woman for as long as I have, I know.
But again, I didn't argue it with her. Her house her rules.
