Friendly reminder: it's good to be assertive, but it's not good to be aggressive, and there's a not-so-fine line between assertive and aggressive, and you cross that line (nay, yeet yourself deep into aggressive territory) the moment you decide other people's boundaries don't matter. Assertiveness is a good thing, but assertive people also take others into account and try very hard to not cross others' boundaries. Be assertive, not aggressive.
