I still search the horses for sale ads as well even though I have no intention of acquiring another horse. Then again, you never know what will happen.
Two years ago I was casually browsing horses for sale in my arena and happened to start looking further south in my province "just for fun". I happened to come across an ad for my dear old gelding that I used to own. I had reluctantly sold him to friends many years ago and then found out he was sold again. I always regretted selling him, but due to life circumstances at the time, I thought it was the best decision for all. Needless to say, after seeing his ad, it took me all of two days to contact the owners, purchase him and bring him home again.
This is a decision I will never regret. We now live on an acreage where we have lots of space and a few other horses. Although Sam is 22 now, he is healthy, happy and still going strong. Had I not seen his ad, I shudder to think where he might be now.
Keep looking, because you never know how your circumstances might change.
