This is why most new thermostats come with stickers that have the letters on them. Put the stickers on the wires according to the terminal letters before disconnecting them. Then put a piece of clear tape over them because the stickers don’t adhere very well.

I’ve saved a lot of people a lot of money (while pocketing a $20 each time) by knowing this.

Your entire argument is based on 2 assumptions: that she is 14 and that I would use the word “boy” to describe a 14-year old male. The female pictured looks 16 to me but I’m sure you’ll dismiss that because it doesn’t fit your narrative. And I refer to males that have reach puberty but have not yet attained the mental and emotional maturity to be labeled a “man” as “kids”, not boys. I rarely use “boy” to describe anyone older than a toddler.

Also, you clearly missed the point of my previous comment and took it personally, thereby becoming defensive. The point being that unnecessarily questioned the OP’s word choice but had the OP chosen the way you suggested, someone else would attack that choice. The whole thing is pointless and unnecessary.

Because if OP put “girl”, someone would accuse OP of toxic masculinity. Besides, the model is obviously past the age of physical maturity so it’s a pointless and stupid argument from either direction.
