Alone we can do so little together we can do so much.

In Genesis, it says that it is not good for a man to be alone but sometimes it is a great relief.

Always give a word or sign of salute when meeting or passing a friend, or even a stranger, if in a lonely place.

When so many are lonely as seem to be lonely, it would be inexcusably selfish to be lonely alone.

If you are lonely when you're alone, you are in bad company.

Look at the sky. We are not alone. The whole universe is friendly to us and conspires only to give the best to those who dream and work.
