MOC Windy (UK card) when she first came up on ebay about 10 years ago. She was my first pony and a super grail for me even now, but I couldn't afford her then and I had to let her go.
And then it goes on because a few months back, around my birthday, there was another one. And I missed her too because I didn't see the auction till after it ended.
I was pretty gutted but at least I know she has a good home with a good owner. One day...maybe third time lucky? UK carded Windy doesn't come up very often :/
