How should I be able to ride when it is raining-blowing-snowing-is mud-slippery and so on?
You may not need to ride that day, you can always come up with other things if you want to spend time with your horse.
I just can not stand to groan when the horse is long-haired and has rolled in the mud, you think, but take the hooves instead! You can, for example, teach the horse to take up its hooves even if you are standing on the opposite side. It is excellent therapy to get the horse to lift its legs when doing it in a certain way and very useful.
You can also teach the horse a little trick when it is in the stable and it is not about the trick itself, but to be with the horse. Learn to listen and understand and have a fellowship with it.
Make “boring” days nice days! We have the horse to have fun and get away from everyday life π
