You hit a tree with an axe so you can do some analysis on it. To do the analysis on the tree, a cross section needs to be obtained, so you must chop it in half with your axe.
The person who is doing this analysis is very sexy (せき). Who is this sexy person? Why it’s you of course, you sexy beast. I love watching you do analysis on trees. It’s so sexy.
