I get a lot of people asking this, but they do it for real, and I’m always like, “what did YOU do to me? You’re one of the sweetest people I know!”
The only way I do a text to more than one person at a time is if they are all linked in the same scenario- sometimes I like to ask just in case I did something and didn’t realize, so, for instance, I sent a specific text to the (four or five) people I worked with this summer. I don’t think it’s impersonal- as there wasn’t a specific thing I was apologizing for, and as I made it very specific to the situation, I think it worked.
