Just milking the cow

The other night Molly came to my room and said she had to tell me a secret. She said she had taken money from Colin's bank. She then put it into Caleigh's and her banks. Each of them have animal banks (cow, chicken, sheep).  I tell her she shouldn't do that and ask her why she did it. She gives me the most serious look and says, "I was just milking Colin's cow for him." What do I do with this child? She has an answer for everything.
