is a rather common female name in Tanzania.
She is also a little girl that lives next door, and is known for not greeting people and crying a lot.
The walls (or maybe it's the roof/ceiling) here are thinner than those of Dupre Hall, so a moderately loud conversation next door is comfortably audible.
At the moment, Happy is crying like crazy, and it seems that her mom is so sick of it that she's making fun of her. It's a pretty funny thing for a mom to do, but this is tonight's entertainment!
