What about other people he knew? Was it just you or was it pure laziness. I did not do this, but it’s an absolute struggle for me to add anyone new these days to the point that ill normally send that first text with the persons name in it so if they call i ignore it then cross reference the number after with my txt to see if its someone i know. You will never know the lengths some people will go to just because of laziness lol. If anything he probably knew your number by heart.
