That would, perhaps, be the wisest rule.

But, above all things, remember that dullness and stupidity--and you will certainly find them in every school--are the very last things to get out of patience with.

If the Creator has so formed the mind of a boy that he must go through life slowly and with difficulty, impeded by obstructions which others do not feel, and depressed by discouragements which others never know, his lot is surely hard enough without having you to add to it the trials and suffering which sarcasm and reproach from you can heap upon him.

Look over your school-room, therefore, and wherever you find one whom you perceive the Creator to have endued with less intellectual power than others, fix your eye upon him with an expression of kindness and sympathy.

Such a boy will have suffering enough from the selfish tyranny of his companions; he ought to find in you a protector and friend.
