She doesn't think about us.

Why do you consider her a friend?

I cannot stand people who are late all the time. It's rude and shows a real lack of consideration for others. I would have told her off.

Being late (when she could have just cut the phone call short) is very annoying. Arriving with potential Covid is unforgiveable. It's time to get rid!

she sounds awful

I’d have made my excuses and left.

And she’s a friend you say ?.

My goodness, I think I’d be questioning just what kind of “friend” she is, especially after she has knowingly been in close contact with someone who has covid and then meeting you afterwards. Unbelievable behaviour on her part, I think. The keeping you waiting was bad enough, but then risking passing on covid to you and your other friend tops it all.

The friend sounds selfish and full of her own importance I would give her a wide berth.
