The sound of my dad in the kitchen, pouring a cup of coffee, circling the inside of the cup with a spoon, tapping the spoon twice on the rim, and dropping it to the counter with a clatter.
Being far away from home, and smelling something that reminds me of mom's cooking.
Halfway through the day, suddenly remembering a pleasant dream I had the night before.
Waking up on a winter's morning to a fresh blanket of snow.
An A&W rootbeer in a frosted glass at the end of a long hike during a hot summer.
Waking up to find the cat snuggled up on my legs.
Discovering something in common with a stranger I got chatting to somewhere.
A student hanging around after class just to tell me something they thought was worth sharing.
Stumbling upon a photo I haven't seen in ages, and remembering the story behind it.
Noticing for the first time a picture I've been passing every day on the wall for twenty years.
Tasting something nice I haven't tasted since I was a kid.
