How to kidnap Tia

Preface: Tia is Peter's cousin, she is a year older than Melynn.  Melly completely loves Tia and any event that they both attend they always disappear off together.

This morning I was telling Melly that Tia was at the deer widows party last night and that I should have brought her.  She remembered the last time she saw Tia at the family campout.  Then she burts out, "I think I love Tia."
"Mom, next time you see Tia, grab her arm, put her in the car, and drive real fast to our house and she can sleep on my floor every night."
"Okay?!?"
What are we teaching this kid?
