hit the send button as a thought separator

This drives me nuts, that's what blank spaces are for. I don't like getting a half-dozen texts that blow up my phone, especially when I'm likely in a meeting or something. A text message should be a complete communication, with blank spaces to separate parts of the message.

For example:

I'll be home late tonight, the meeting went long. Should be there in 30 min.

BTW, should I pick up something for dinner?

My SIL would send that in like 7 texts somehow, whereas I'll send just one. I find it impolite to send so many, so I go out of my way to spend a few extra seconds making it nice for the other person to read.
