I can tell from the aroma that teacher's day is coming.

My sis never fails to prepare something on teacher's day.
Last year, it was melted chocolates with popcorns. My recipe. This year, it's butter cookies with chocolate chips. She got the recipe from my aunt.
She've been baking with my mum since last week, and I'm smelling baked butter cookies almost every night.
It used to be burnt smell. Today, it smells much better, but I'm sick of the smell already.

Please let teacher's day pass by quickly.
