Have a place for everything and keep the thing somewhere else; this is not advice, it is merely custom.

It is my custom to keep on talking until I get the audience cowed

Custom is petrification; nothing but dynamite can dislodge it for a century

Laws are sand, customs are rock. Laws can be evaded and punishment escaped, but an openly transgressed custom brings sure punishment.

We are strange beings, we seem to go free, but we go in chains - chains of training, custom, convention, association, environment - in a word, Circumstance - and against these bonds the strongest of us struggle in vain

They're custom. They're not like your everyday tablets like you've seen from the bigger manufacturers.
