My take on this is there's constantly a "friend or foe" subtext to everything that's going on. So you have to be careful about how you state things, or you're going to subtextually saying "I am a foe" or "I am attacking you". This is context-dependent. If someone is e.g. coaching you in something, it is expected they'll critique, and that will not carry connotations of attack. There's also a level of closeness where giving someone shit is actually affectionate. Etc.
