Wagtail
Horse servant
I love both but if I had to choose, it would be mares. I used to think all mares were aloof and could take you or leave you, and that geldings were more affectionate and loving. However, my mare is the most affectionate, cuddly horse I have ever come across, and she beats all others hands down. My gelding is lovely too and quite soppy, but I would say he is far more quirky and 'mareish' than my mare is.
