Because of Copyright laws, of course you did the right thing. A lot of younger people don't know about copyright, so they need to learn the hard way. It did remind me of a time, back in the day when I was almost 30 years old. We didn't have a cent left over after at the end of the paycheck. We owed credit card charges. We lived on a teacher's salary, which in 1972 was just at the poverty line.
An acquaintance (We weren't what you would think of as friends even) started going to Weight Watchers meetings. How I wanted to lose weight, and I desperately wanted to go on Weight Watchers too, but I couldn't financially. I phoned her every week and asked what she learned in her meetings. I needed all the details, and kept her on the phone much longer than she probably had time for. This went on for weeks. She was very gracious, but towards the end I sensed that she was a little miffed, and rightly so. She was paying, going to meetings, and I was getting all this information free. I only wish I had made sure she knew how much I appreciated her patience with me, but, me, young and dumb probably just said "thanks" and that was the end of that. She never did tell me "no more."
Now at age 71, I could have at least given her a little appreciation gift. I have grown up finally, and when I get upset with my grandkids, I have to remember back when I did some of the same stupid things they are doing.
Maybe that FB lady is young and doesn't yet realize protocol. It is a good thing for her to learn now though.
