I am gonna need 15 year olds to be 33% less annoying, though, in return. I mean, I was incredibly annoying at 15 and I get it’s hard not to be but goddamn meet me part way here
Can you give some more context for your question? It sounds like you might be replying to someone who just expressed a desire for something that you also want, but the specifics of the situation might make one reply feel more natural than another.
But based on nothing else, I’d say “I want that.” Or “I want that, too.” sounds natural to me, an East Coast American in the NYC area.
Also, looking at your posts, your English seems pretty natural, I wouldn’t guess you’re a non-native speaker reading what you write online. I can see some over-formality that I know to look for something deviant, but it’s not immediately apparent.
