PBC #7: Nuns

Here is the new Paper Boat Challenge. A real one again. You know the rules: Try to find the solution until Monday next week (9th July). You can ask questions, I'll try to give hints. There are no excuses this time;-) (The cartoon is not part of the puzzle.)

Once there were two nuns. The first one was called Sister Mathematics and the other Sister Logic.

One day they left their convent together and went to the nearby town in order to sell vegetables from the garden of their convent. On their way back…

M: It’s already getting dark and we are still far from the convent.
L: And, my Sister, look, there is a strange guy half an hour behind us.
M: Yes. What do you think, he wants.
L: It’s logical. He wants to attack us.
M: Oh my God! According to my calculations he will reach us in half an hour if we continue at this pace. What could we do?
L: The only logical thing to do is to go faster!!!
M: It doesn’t work!
L: Of course not. He did the only logical thing. He began to walk faster, too.
M: And now? What shall we do? In one minute he’ll reach us!
L: The only logical consequence for us is to separate. You go that way I’ll go there. He cannot follow both of us.

The strange guy decided to follow Sister Logic.

Sister Mathematics got to the convent safely but worried a lot about Sister Logic.

A few minutes later Sister Logics came to the convent, too.

M: My sister, thanks to God you arrived as well. But tell me. What happened?
L: It happened what was logical. The guy couldn’t follow both of us and chose to follow me.
M: And then, what happened?
L: That’s logical. I started to run as fast as I could. He did the same.
M: And?
L: Again that’s logical. He reached me.
M: My God! What did you do?
L: I did what’s logical. I raised my habit.
M: My God, Sister!!! What did the guy do?
L: He also did what was logical...
