New Phrase: せっけん　（石けん）
Meaning and Thoughts: And another word from the public bathroom. This one was also understood as soap but i didnt know the reading, and in fact I had never heard of this word before. it had always avoided my knowledge, until now!

New Phrase: せいご　(生後)
Meaning and Thoughts: So I was sitting down on a toilet in a public restroom, and i noticed a baby chair and it said something like 生後５月から３歳まで and i was really proud of myself for understanding from context that this meant "after birth" but i wasnt sure how to read it, so i looked it up and found the せいご reading which makes sense.
