My dad once suggested I take some daughter of a friend of his out to ride my horse (she's like 14, a rude little bitch and weighs significantly more than I do and I'm in my 20's) because she liked horses.  I was like hell no I am not doing that to my horse, he's a good boy so I lied and said he pulled a shoe (I've had him barefoot the past year) and his foot was a little sore from it so he couldn't be ridden until the farrier could come by (all of his feet would be sore if this beast was allowed on him).
