Here are some simple things that bring a smile

The smell of a first rain
Eating pakodas on a wet rainy evening with hot chai
That perfect coffee on a chilly night
Friends sitting an sipping whatever by a campfire outdoors and chatting
Reaching home for a long vacation
Eating vanilla ice cream with hot chocolate sauce
Drinking a perfectly chilled beer after a long hard week
A bouquet of newly sharpened pencils on your desk
The spray of waves kissing you face as they crash on the rocks
Looking down upon clouds

Do you have any more to add…
