A short, finished list rather than an endless feed: 5 of the best mother's day quotes ever written, picked out of the full mother's day archive on QuoteForever. You will find Stevie Wonder, Victor Hugo, Henri De Toulouse-Lautrec and Gilbert Parker among them.
Read the list top to bottom, or use it as a starting point - every author name links to everything else they said, and every quote has its own page you can share or turn into an image.
