I guess it’s mostly an Awwww. But then, some questions are raised but not answered. Mainly, what’s the joke? Between panels 2 and 3 it changes from two pairs of tracks to one pair — is it meant to be a puzzle, solved by the reveal in panel 4 that one skater is now carrying the other. 

Also: In the first panel, are all the skates drawn correctly facing the way they are going (or are the red ones wrong)? Where we see two pairs of tracks, are they equally skillful or is one more wobbly? In the final panel, are the tracks especially wobbly, and is that sort of the joke?
