Ingratitude is always a kind of weakness. I have never seen that clever men have been ungrateful.

Failing to acknowledge help is usually not malice but a small inability to admit you needed any. Saying thank you means saying you were not sufficient on your own, and people who are unsure of themselves find that costly. The ones who see clearly do not feel diminished by naming where their advantage came from, so gratitude comes easily to them. What looks like coldness is often a thin sense of one’s own standing.

Think of one person whose help you absorbed without comment. Tell them this week, specifically, what it made possible.
