And who'd oppose a little tricking,
Which brings yourself a deal of picking?
And where,—to use an honest course,
The saddle's put on the right horse?
Keep, then, those shopkeepers in view,
Who'll more than wink at all you do;—
In short, trust no one (to save trouble),
That won't make out a bill for double.
Mind nothing but your own affairs,
And let the rest attend to theirs.
