Status Updates From Beowulf

"well actually, buddy, sit down, you're drunk.
unferth, you've run your mouth about breca, me
and our sea-swagger, but let me drop some truth
into your tangent. i've been better on the water,
deeper in the srink, and stronger in the swin,
than any man alive. breca and i were boys
together. our desires were only dares, one upon
