Is what I typed to my friend, and when I read it to myself, it sounded horribly awkward. I'm drawing a blank on what it should it be. English is my native language, so this is really bugging me. Can someone please correct it?
ETA: I suppose it's just me. Thank you everyone for your input! If I were to correct it for myself, I like "How come people don't know how to loop gifs?" but that's a personal thing, I suppose. Please consider this resolved, unless someone might have an idea of why the construction sounded odd. :)
