I was texted by a close friend when another close friend was in a serious car accident, and texted back for details. It wasn’t because we were being impersonal, though. We were both freaking out and she was trying to help calm me down a bit with some of the information she knew. Text for whatever reason seemed more appropriate.
I guess it’s different where I am. People rarely have time to have a whole phone conversation, and when they do, the person they need to call doesn’t have the time. Leaving voicemails becomes very cumbersome, and they often cut in and out. So, we text the information, and it becomes habit.
And, texting does have some perks. It’s much more private; everyone’s usually out and about, so texting them something gives both of you the opportunity to have a quiet conversation. It’s easier to understand; cell reception can get pretty bad, or background noise pretty loud, in some places. You can edit; say only what you really want to. Conversations can be held at whatever pace you need at the time; no minutes ticking by while you think.
I’m not saying it’s a great practice, and some things probably are more appropriate with voices or in person. I’m just saying what it is where I am.
For sure, if a lot is being said, and talking would be easier than thumbs, one’ll ask the other if they can talk at the moment. Then the other’ll call if they have the time, or send back a “no, sorry” when they get another moment to type.
