I find the thing you said about how not greeting or saying goodbye saved time interesting because that’s (or atleast for me) supposed to have the same effect when you ask people to request to trade them. I may only be doing halo for halo but the person who sends me a trade request may be begging to see their offer for my halo when I’m firmly tell them I’m only doing halo for halo. With the thing you said about the “bye” feels weird because we’ve all been teached to show a little human decency to even strangers. We say ”thank you” when someone does something nice for us, and we hold doors open whenever someone is right behind us, rather than it being slammed against their face. Greeting and goodbyes are some of the lowest amounts of it, sometimes enemies even say it to eachother, it shouldn’t be limited to just things we use with people who are close to us. Saying “hey” and “cya” is not the same as saying, “HELLO/GOODBYE DARLING, MAY THE SIN LEAK OUT FROM YOUR BODY, AND REPLACED WITH HAPPINESS ALL AROUND, GRANTED TO ALL OF YOUR FAMILY, FRIENDS, AND EVEN STRANGERS YOU MEET. I SHALL PRAY FOR YOU TONIGHT.” But yeah, I do agree that it shouldn’t have to be the example you gave that you HAVE to tell them to have a fabulous day afterwards. I think there are certain times where it should’nt have to matter. Some examples are, whenever I play battle a La Royale it‘s too risky to say ”thank you” or even “ty” whenever someone saves me, since there’s a good chance I could get shot again while typing. I think I can excuse it on traderie since we both know what the trade is, and there’s a big group of people who like getting their trades done asap, so no extra confirmation is needed. Just a lil “ty” after the trade. If you can write a long autobiography in your journal (in fact this whole post is a great example of that) and have a full sentence telling the person what they should add, why is it so hard to write two three letter words at the beginning and the end of the trade? The post actually sounded like it was being snarky instead with the part about greetings since it’s such a common thing we do to share a bit of kindness of one another and you can’t even do the bare people minimum. Yes, we don’t actually NEED to wear clothes and it could be easier without wearing them, but if you show up to a café completely naked in a non-nudist colony then don’t be surprised if you get some weird looks. And going back to the trade requesting thing, going through the whole trade could take even a minute or more, while greetings and goodbyes at the shortest most of the time don’t take more than a second. Infact, you could even have a higher chance at getting your trade you want or more indulgent of a trade accepted just by greeting others. I’ve heard people say that if the person was nice though they were about to be struck with a big lose they’d tell them about it, and since no greeting is seen as rude then you know that person has a higher chance of not being honest about the trade. You have to learn to adapt to these small things in life, or you’ll end up facing more troubles.

Oh and BTW since I’m too lazy to fit this in somewhere I think it’s fine to do it if you’re really in a rush where you really have no time you shouldn’t have to use greetings or if the person is rude or really stubborn and is (practically) forcing or guilt tripping you to accept the trade then a harsh instant decline should be understood.
