Texting has brought my wife and I closer. I am very busy and have a 1.25 hour (each way) commute every day, standard business week. She has a job that works weekends.
I go to bed around 11 or 12, she stays up to 1 or 2 weekdays.
I get up at 6, out the door by 7. I work until about 4 or 5 and then drive home. On days when I teach (usually 2-4 days a week- two semesters a year) I go to the University until about 9 and I am home by 9:30. Eat dinner, kiss wife, play some EVE online or something, go to bed.
Weekends are better, but since museums are open on weekends, that is when she works. So I sleep in a little, get up, we see each other for an hour or so before she goes to the museum and then I do my thing until she comes home.
We did this life for 10 years. Mostly happy, but I always wanted to spend more time with her. She is after all, my best friend.
Then, just 3 years ago, we decided to get cell phones. Yes, besides my work phone, we did not have a cell phone. We were kinda like you, “why this craze. this is silly. look at those silly young people and their texting.” Nothing ever mean, just a “meh, we don’t need it”.
Now, instead of the 1-2 “check in” calls a day, we share tiny snippets of our day with each other. She sends me a pic when she sees something funny, or when she has a thought. I send her a frustration I am dealing with and she talks me down from the ledge.
This is done in 10-15 word texts, taking just seconds. Not pulling me out of my work in any way and not hurting productivity. I mean, as I walk from one meeting to the next, i am just looking down at my cell and sending a “lol” response to the pic my wife sent of our dog nuzzling a stuffed fish we bought him. Or, I am seeing her supportive statement of “don’t let them get you down, you know your better than that” in response to my quick text an hour ago saying “these people are driving me nuts, they want me to …”.
So, to answer your question. I am texting about my life and sharing it with my wife in tiny little snippets. I am calling her on the phone when I am driving and laughing at the texts she sent me earlier, or the meme photographs she or I send each other. “Hey honey, we got a call from that dude who wants us to sponsor his (insert crazy political position) again”. Response “(Picture of grumpy cat with “NO”)”. A quick LOL and a simple warm interaction with the woman I love.
Let it go dude, humans communicating is fun, and caring, and enriching and loving. If they do it while they should be working, driving, or other things? well then you got a beef.
Carrying a child? Maybe, I don’t know, would have to know the whole context. Did you ever answer the house phone (land line) carrying a child, or place dishes on the table or some other task? I know I did. I would have to know the full context to be concerned.
But, to answer your fundamental question of why people text… Maybe it is because they have people they love and they just want to spend every tiny second they have, in between the chaos of their busy lives, with them.
Crazy stuff, I know.
