Don't fish between two rivers
Unless you're a good swimmer
And the two streams don't meet at the center.

If the old dog can't learn new tricks
You don't have to buy it a bag of treats
But don't argue with it on politics.

Don't play with fire
But if you really want the ointment
Then get burned to your heart's desire.

Patience is not always a virtue
The mousetrap always looks pretty harmless
Until it breaks the rodent in two.

If you came and saw but didn't conquer
Perhaps there really was no war to wage
And you have just gone bonkers.
