I have often seen people uncivil by too much civility, and tiresome in their courtesy.

Courtesy is a science of the highest importance. It is ... opening a door that we may derive instruction from the example of others, and at the same time enabling us to benefit them by our example, if there be anything in our character worthy of imitation.

Too much sensibility creates unhappiness and too much insensibility creates crime.

It is important not to trust people too much.

Hopefully I don't annoy people too much.

I enjoy scaring people too much to let it go!
