Can I get pregnant?

In a second grade class, a little girl asks, "Teacher, can my Mommy get pregnant?"

"How old is your mother, dear?" asks the teacher.

"Forty."

"Yes, dear, your mother could get pregnant."

The little girl then asks, "Can my big sister get pregnant?"

"Well, dear, how old is your sister?"

The little girl answers, "Nineteen."

"Oh yes, dear, your sister certainly could get pregnant."

The little girl then asks, "Can I get pregnant?"

"How old are you, dear?"

The little girl answers, "I’m seven years old."

"No, dear, you can’t get pregnant…"

Then, then her classmate Dyoknoy who is standing behind her gives her a poke and says, "See, I told you we had nothing to worry about."
