He: Random ramblings that apparently have to do with cars or engines or some such nonsense.

Me: You do realise you're speaking Chinese right now right?

He: Okay on a rear end theres a straight part that goes up and down and flexes so if you add some springs it....

Me: Alright now you're speaking Spanish, which means I actually know some of those words but didn't understand the sentence at all.
