Now is the age of SNS, young people may not write New Year 's cards.
When I was a office worker, I used to exchange New Year 's cards even inside the company.
Even though I know that this is obviously a bad habit, nobody tried to stop it. I wrote more than 200 New Year cards at that time.
It seems that total number of New Year cards tends to decrease year by year. There are people declaring that they do not exchange New Year 's cards any more. I realize the change of the times.
I bought 30 sheets this year.
