I personally think that the people who can’t be bothered to actually write authentic messages, and assume that everyone will just read their word salad full of repetitive AI patterns, are being the ones acting entitled.
likewise for friends (not just your girlfriend), getting to know you is part of developing friendship.
so family, friends, work, business, that pretty much covers everyone you deal with on a regular basis.
i would go as far as saying that if you don't trust me then you have no business even communicating with me unless the interaction is incidental.
True: Nobody is entitled to be treated nicely. Nobody is entitled to an open, friendly relationship. Nobody is entitled to get to know you. If we only did what we were entitled to do, and received what we were entitled to receive, the world would be an even shittier place than it already is. We have enough people walking around with the "You're not entitled to me being nice, so I'm not gonna be! nyaaaaa!" attitudes.
If your comment is at all indicative of how you are in real life, I really don't think you have to worry about people wanting to get to know you.
