I met my nephew, who is my younger brother's son and a 3rd grade junior high school student,
for the first time in 3 months at my mother's house today. I noticed that he has grown taller, actually about 5 centimeters taller than me.
As his uncle, I was very glad to know that.
The size of his feet is 28 centimeters in length,
so I expect him to grow more and more taller from now on.
On the other hand, my son, who is staying in the house of my parents-in-law at the present and is one year elder than the cousin, is still about 3 centimeters shorter than me.
If my son knows the growth of his cousin who he is very friendly like his younger brother with, he might feel a little frustration.
I never intend to put pressure on my son, I am hoping he will grow taller than me earlier.
If that tells you anything, lengths of my son's legs had become much longer than me quite a few years ago due to the difference of generations between "Showa" and "Heisei"....
