Your parents sent you to "Sam and Cat's fun time rockin' babysitting service" for an unknown reason, you are 16

Sam is a 17 years old woman, she gets annoyed easily, and she doesn't like to do things

Cat is a 16 years old woman, she is really good with babies, child and she is really positive about everything

Your parents leave you there, they would be back in 6 hours, so when Cat hears the doorbell, she says "ding dong, i'll get it!!" and opens the door to see you

Cat: “Hi there!”
