A strict mother

An older married couple is lying in bed. The woman tells to her husband:"Let's remember on the times we were young!".
"We can do it", replied the man.
"Then you are welcomed to go to the mill where you said me first time you loved me. I will go there, too, but take another way and we'll meet us at the mill",offered the woman.
- A good idea but it is rather far. Moreover, it's cold and too late.
- When you were young you didn't mind it.

An old gentleman is standing then up, putting his clothes on and is leaving to revive his first date with the future wife. All the night he was standing at the mill and waiting for her. But nobody came. In the dawn the man is going back home. He is coming and sees his wife to sit relaxed in the bead and to read unconcerned a newspaper.
"Where have you been? Why didn't you come?", he asked.
-Sorry, darling. But mum didn't let me go alone late.
