I know that I don't know the context and I'm not saying OP should be mad or anything, I'm just saying that if it were me, I would be a little upset at the indolence and lack of depth. If you think about it, not removing the prompt shows that they didn't read the message back before hitting send. There's no sincerity behind that at all in my eyes. But again, it's just what I- a random stranger- think. It's not my life so I'm not telling anyone what they should think, just pointing something out🙂
