失 (Lose / Excuse Me 失礼) vs. 知 (Know) & 天 (Heaven): The Top Poke-Through Rule
Does the center sweep poke through the top horizontal line? If NO, it's 天 (Heaven) or the 矢 (Arrow) inside 知 (Know). If YES, something slipped out the top and was Lost: 失 (Lose — 失礼します Shitsurei shimasu)!
Every single day in Japan, people say 失礼します (Shitsurei shimasu — Excuse me) when entering a room or hanging up the phone. Literally, 失 (Lose — shitsu) + 礼 (Politeness — rei) means 'Forgive me for losing my manners for a moment'!
