Duolingo's Lives System is a bit... 

... Shit, I know that the whole practicing for more lives is possible and keeps up your streak (along with super duolingo), but it's really tedious to do.
Anyways, go subscribe and leave a funny comment or whatever!
The Duolingo bird is a green little shitstain bird that does language things and flies around and is a bird and language learning and other things haha
