Some simpletons, too busy with what they want will importune you and then ask for a favour. To do better than this, when you petition think people! Care to understand them if you need their understanding. This reminds me of a story:
Nasreddin was repairing the roof. Not easy to climb up when you are beyond your first youth.
A neighbour called him from the street.
“Come down, I have something important to talk with you.”
The Mullah climbed down from the roof with some pain.
“What is it?”
The neighbour whispered into his ear, confidentially:
“Can you please lend me five silver akce?”
“Come up with me.” said Nasreddin.
The man worked his way up a creaky ladder after the Hodja. This took some time, as Nasreddin was old and not so quick. Finally on the roof he asked again:
“Can I have the money now?”
Nasreddin leaned over and whispered confidentially into his ear:
“I’m so sorry, I do not carry my purse with me when I'm repairing the roof.”
