The text on the plate says (in Dutch):
Sing, fight, cry, pray, laugh, work and admire. A well -known Dutch saying. Work and admire. No, not: drink, sigh, pout, sit, complain, watch and lick wounds. Or stink, fight, crawl, lie, bark, die, cheat. Work and admire someone every day, give a compliment, that is the foundation to collaborate.
