Translation:I, my brother and my cousin play all day.
No. It's "I play" not "Me play"
But the correct form would be "My brother, my cousin, and I" Only thing is that rule (of putting the first person pronoun at the end of a list like this) doesn't exist in Hebrew. It seems maybe the opposite is true in Hebrew (ie it's actually standard to put אני first in a sentence like this).
Shim, I agree with you that the correct answer in English is to say, "My brother, my cousin and I play all day long." Duo marked me wrong on this, and I am reporting it.
