Happiness is..

eating a packet of Milo on your bed without any worries that your mum will tell you that a colony of ants is going to pay you a visit.

..but..there are three consequences that I might suffer:-

1. Sore throat (again) if I forget to drink enough water after this.
2. Toothache if I forget to brush my teeth.
3. ..and a colony of ants paying me a visit, of course.

Moral of the story - 

Happiness is inevitable, even when you have topic tests ahead of you. Even when sometimes you feel that you just cannot breathe. Even when you start to miss your family.

Happiness is...

still there. You just can't avoid it.
