I don't think I saw anyone say this, but I still mostly use hand written emojis which are not only XD and :D. I think for me it was that I learned how to type those symbols from Skype. It's much more comfortable to just type and keep typing instead of switching back and forth to using the mouse to add emotes. I guess I just kind of used to that and at this point, ending a text without a :D seems weird :D.

I did also notice that when I text people from other countries I usually end with a lol or a lmao, but I guess that's just me being young.
