Sempi had this conversation with Yoshi yesterday.
Sempi: Amma, when can I have a baby?
Yoshi: Well, you have to study hard. Finish your pre-school, then your elementary school, middle school and then high-school. Go to college, well that part is optional. Get a job, meet someone, fall in love and then you can have a baby. Most importantly you have to be at least 18 years old.
Sempi: Man, I'm never gonna have a baby.
Yoshi: Why do you want to have a baby?
Sempi: So I can fiddle with my own baby monitor.
Previously, Yoshi had told him not to play with Vian's baby monitor and this is his solution. :)
