To feel irked when people have full on conversations on FaceTime in a public rest area?

[Yellowleadbetter]

I was at training last week.
Every break and lunchtime there were at least 2 people having full on FaceTime conversations with people in the rest area.
About shite though.
Nothing of importance was discussed, just what you doing? Has the dog been out? what shall we have for tea? (No MH issues btw)
These convos went on for the entirety of the breaks.
Loud.
It bloody ruined peaceful breaks on a tough and intensely packed training course.
It was impossible to have conversations with others on the course.
It’s antisocial & selfish isn’t it?
Infringing on every single other person there.
Why the fuck do people think this is ok? Go and do it somewhere else ffs.

Show me my arse if you don’t mind this, but it got right on my nerves.

YANBU.

DP & his family seem incapable of conducting a phone call the old-fashioned way, so at least once a day one of them virtually bursts into our house via his phone screen. I try very very hard to tolerate it because I know it's really not a big deal in the grand scheme of things but it's so different to how I operate that it's a struggle for it not to grate me.

(I very very rarely even speak to anyone on the phone outside of work, and if I ever video call at home it's usually a special occasion with a set time to call so I can set the laptop up and have a drink ready).
