The violent attack of the lower year vs the lowly ruffian of the upper year.
Relaxed, witty and humorous.
——You raised me for the first seventeen years, and I will support you for the rest of my life. It's reasonable.
——There is no problem with raising it, but why did you come into my house in the middle of the night? Eh? Why are you still in bed?
Laughing at the fact that the father deceived the son in the first seventeen years, and the son deceived the father in the second half of his life!
