A smile costs nothing, but it gives a lot๐ It enriches those who receive it without impoverishing those who give it. It lasts for a moment, but sometimes remains in the memory forever๐ No one is rich enough to do without it, and there is no poor person who would not become richer from it. It creates happiness in the home, creates an atmosphere of goodwill and serves as a password for friendsโค๏ธ
