Sometimes the best people you know may be wholly unaware of their quality, or even think they lack worth. Remind them. Remind them of their worth, that you are honored to be in their company, that they matter. It may seem a small thing to you, but not to them.
@coachgowron Since Willie was home late, I ate his dinner. So I told him that he was worth a dinner to me.
He didn't seem as impressed as you said he would be.
