"A Birthday" looks like a pretty straightforward party on its surface, but it helps to be familiar with a slew of Christian symbolism if you really want to get in the swing of things. Don't worry, though, we've got you covered over in "Shout Outs." And if the vocab is making you uncomfortable, we translate all of that in the "Detailed Summary." You'll be saying that this poem is cake in no time.
