Sure, I didn't ask her, but I tHoughton I was doing her a favor. She in turn, tells me that she had spent 4 months aquire ng that many, so she could finally live her dream of walking around with a leather belt pouch filled with all these coins.
I told her that was ridiculous and she walked out, into the woods. How do I fix this?
Normally the Gold coins are worth more than face value and have collector value. You took something that was not yours and did something with it that the rightful owner did not want. You will have to regain her trust over time since you have proven to be reckless with her assets. If you continue to be irrational it will get worse and never be fixed.
Get them back this instant. Why did you do it without asking her? She is mad because you didn't take her consent.
I'd replace them, apologize to her, and start to respect her ideas and thoughts. It was selfish of you to do that.
You buy them back. Yes you will loose money on the exchance both ways, but that is the best that you can do.
I'd take the paper money and use it to replace the coins.
Apologize and get them back.
"... Sure, I didn't ask her, but I tHoughton I was doing her a favor. ..." --
See, that's your problem. You need to leave all the tHoughton to her.
get them back and more ......
