When the mom leaves smile kindly and wave pretending that you didn't see what had just happend.
Nothing. Because he/she deserves it anyways after all he/she did to you and your friends.
They are people who should be the ones telling you rude comments but then everyone will laugh it off because it's just a joke.
They are people who you should be able to trust and support you and not put them down.
Whine and complain saying that she's ruining your life.
Tell your mom you never really wanted to go there after the trip in the best and kindest way you can.
Cry or just feel sad.
Cry because who else will give you the most birthday presents?
When they come out of your mouth it feels like you have taken concrete blocks off your shoulders.

Laugh harder to give the teacher an even harder time.
Try your best to stop.
