AIBU to find friend texting while chatting rude?

[Jng1]

Have a friend - both with kids at same school. Mostly get on fine, but I find the way she prioritises her phone over everything/everyone else so rude!
So, we'll be in a cafe having coffee and catching up and her phone will always be face up on the table. If I'm chatting to her and she's gets a text she'll immediately check it and start replying. I've now started pausing whatever I was saying and waiting for her to finish, but sometimes she just looks up and says 'go on, I'm listening' when she clearly isn't!
She even interrupts her own conversation to answer texts.
I've asked 'has something urgent come up?' But it never is - no, it's just her mum, or her sister, or partner asking something.
Why do people do this? It's so rude.

bring a book or a newspaper and read it every time she looks at her phone. She'll get the message.

I couldn't agree more, it's so rude. I have a 'friend' who constantly does this. I have now tried to limit contact with her, but I if I told her why she would be incredibly aggressive about it.

Yanbu. My teens are slightly addicted to their phones. They just aren't mature enough to get them in perspective. I find I label as immature anyone who can't leave their phone alone!

But I have rules with my children. When me, dh or any other older person is speaking to them, they must not look at their phones. No phones at the dinner table either or on nights out with us.

Your friend is rude. I would have to say something!
