People like mocking the younger generations about never getting off their phones, but the 50+ crowd is much more entitled to your attention.
"what the hell, man?!?! I texted you and you can't even give me a response for FIVE HOURS?"
"hey what's going on" 13 min "You there?" 23 min "are you busy or something? This won't take long" 36 minutes "????"
then you get a bigger gap where they give up, maybe 3 hours, maybe a day if you're lucky
