So, what happens when someone sends you a text (or a photo) and you don't receive it? And how are they supposed to know that you didn't receive it, other than asking you (all annoyed) "why didn't you respond to my text?" To which you reply "I never got your text!" Which of course causes a whole set of new problems - do you believe someone when they say they didn't get your text? Or do you assume they are covering for the fact that they got your text but forgot about it, or didn't want to deal with it? Having sent texts that were never received, as well as not receiving texts that were sent to me, I don't jump to the conclusion that someone is "covering up" anything. But I do find it frustrating and lack a good solution to this problem. When I text someone to let them know I've arrived to pick them up, it's frustrating to wait not realizing the text was never received, all the while they are inside wondering where I am. Yes, an initial phone call could remedy this, but texting is so convenient, that until it is INconvenient, you don't want to do the complicated phone call. Unreceived texts lead to a lot of misunderstandings and resentments...
And really, where do these texts go?
My phone says the message was sent - I can even tell you when. Yet it never reached the recipient. Is it out there bouncing around the airwaves, waiting to be picked up by some errant device?
And if you are out of service for the moment it's sent, why doesn't it arrive later, when you are back "in service"?
Is this the modern version of "if a tree falls in a forest and no one is there to hear it, does it make a sound?"
