No, I would never. I don't even like when Google gives me suggestions for automatic responses to something. It's so wrong. If I found out my SO did this, I'd yell at her and tell her NEVER to do it again and try to explain to her why it's wrong but I'd probably fail to articulate it adequately. I'd consider just breaking up with her instead it if it weren't for the fact that I'd be very lucky if I even had an S/O.
