February Proverb: People in glass houses shouldn’t throw stones.
Google translation: ガラスの家の人は石を投げるべきではありません

According to Poem Analysis the proverb, “those who live in glass houses shouldn’t throw stones” is often cited as originating in Chaucer’s epic poem, “Troilus and Criseyde” written in 1385. The original text is:
“And forthi, who that hath an hed of verre,
ffro caste of stones war hym in the werre.” (lines 867 & 868 -Book II)

Basically, the proverb is a reminder that people should not criticize others for a flaw that you yourself possess. In other words, don’t be a hypocrite.
