Whose Birthday is it?

Whose birthday is it? It's not Jacob's (his was January 24th). It's not Zarni's (he turned 2 on March 12th). It must be Brenda's! And it's April Food's Day! I don't know how old Brenda is but she can't be too old, because she is my younger sister and we are both very young and beautiful. And look, she is wearing a princess hat!
