If a donkey is tied to a peg, and he is in a bad mood, he can uproot the peg and run away…
This should never happen, so in the olden days, wise people used to tie donkeys in pairs instead of pegs.
By doing this, both the donkeys do not move from their place…!!!
Because if one of the two tries to run away, the other pulls him in the opposite direction.
And thus both the donkeys stand peacefully in their place.
