Nor masquerade

The amusements in the square besides the cathedral in Strasbourg are spinning.
Where is the line between being youthful or childish.?
A grandfather, with 2 grandchildren not teenagers yet, asked.
Told that I meant that it was decided by oneself.
He thought it was good with these paper masks – “then no one sees how old I am”.
Before he again again took a carousel ride with the grandchildren.
