This sign has hung in my parents house for 30 years. Have always loved it. During visits when my kids were younger...and even sometimes still...we will just point at the sign and wag a finger. No words are necessary. https://counter.social/media/I1pRVHHWqaDHI_D9Me4
@estherschindler they used to have another one that said , "Kindly control yourself," in German or Polish. Probably German since I recall it starting with 'Bitte'. Neither of them spoke those languages so it was especially....special.
