Fresh-picked strawberries (thanks, Grandma!)
Grandparent visits and pony rides
Garage sales and lemonade stands
and
Frequent lunchtime conversations as a family:
Lily: "What does 'learning' mean?"
Mom: "When someone teaches you something."
Dad (wrinkling his nose at Mom's response): "It means a somewhat permanent change in behavior." (What a cute scientist :-)
Lily (with a sarcastic tone and mischievous grin): "A change in your behavior, Dad."
Dad: "A change in your face's behavior."
Lily (without missing a beat) "A change in your Mom's behavior!"
Since that was met with a round of laughter from Mom and Dad, a few minutes later another attempt at humor is made.
Lily: "Dad, if you don't give me that, I will punch you in the face."
Mom: "Oh Lily, that isn't funny. We don't say that."
Dad: "Yeah, it's not funny and it doesn't scare me."
