And I looked at it, and I thought a bit, and I looked at my frozen chum; (line 43)
So, this is sort of about friendship, but we think it takes a pretty dark, ironic look at it. The phrase "frozen chum" is actual kind of funny – he sounds more like a popsicle than a buddy. This poem definitely has something to say about the importance of friendship, but it never gets sappy about it. This biting humor has a lot to do with making the poem fun to read.
