Exactly. The other post was weird.
To single out "especially" at the interval at a time when that's not bothering anyone as being somehow more annoying than in the middle of a show 🙄
If I'm on my phone I'm either doing something useful so making use of 'down' time so I can then spend my limited free time talking with people i actually known and like, or something like duolingo so actively learning something . I can't see how an awkward conversation with a random stranger next to me is somehow morally superior or beneficial.
If I go with someone I know i would usually chat with them rather than going on my phone, but I tend to also lift share and go for dinner before hand, so if I do check my phone i dont think 2 mins of non-engagement when we've spent 5plus hours together is an issue!
