Forbearance is no acquittance
For the love of the game
Fools rush in where angels fear to tread
Fools never know when they are well
Fools may sometimes speak to the purpose
Fools grow without watering
Fools and madmen speak the truth
Fool's haste is no speed
Follow the river and you'll get to the sea
Fish begins to stink at the head
Fish and company stink in three days
First think, then speak
First deserve and then desire
First come, first served
First catch your hare
Fine words butter no parsnips
Fine feathers make fine birds
Feast today and fast tomorrow
Faults are thick where love is thin
Fasting comes after feasting
Far from eye, far from heart
Familiarity breeds contempt
False friends are worse than open enemies
Fair words break no bones
Fair without, foul (false) within
