So, the daughter of a Vetrinarian goes off to college in another state.
She is following in her fathers footsteps and is studying to be a vet also. After about 3 weeks of school, she writes to her father,
"Classes are far apart and I could use a bicycle to help me get to them quicker, please send some money".
The father sends the money, but, by chance, one of the other students is finishing school and has a pet monkey that he can't take with him, so the girl buys the monkey with her bicycle money.
After about a month, the monkey develops a serious skin rash and his hair is all falling out. Nobody at the school is able to cure the beast, so the girl decides that her experienced father might be able to help. She writes,
"Dear Dad, all the hair is falling off my monkey, what should I do?"
A few days later, she recieves a reply from her father, he writes, "Daughter, sell the bicycle"
