Today I shall lift up a friend in need.

Here the bum spoke to a smiling old lady, and asked her if she would be kind enough to watch my things for a moment while he and I entered the library.

You may feel you are helping the drowning man but you are only precipitating your own disaster.

After conversing for a few minutes, the friendly bum told me to follow him.
