There are large things of loveliness like the Aurora Borealis, the enormous flocks of Canada Geese during migration, or the doctor telling you that you don't have cancer and then there are the small ones. The small ones are so plentiful, and sometimes so fleeting; we just have to remember to value them.
A bouquet of flowers a propos of nothing, just arriving out of the blue.
A manila envelope full of fridge art, from faraway grandchildren.
A sticky kiss embellished with runny nose from a sick toddler.
Being told by a complete stranger that you have magnificent eyebrows.
A bed filled with pets on an ice cold morning.
A freebie from the photo book people.
Finding a 5 times folded twenty dollar bill in the laundry.
Having a rhubarb harvest after 5 years of nothing.
Going for lunch with really nice people.
Holding hands with your true-love after 100 years of marriage!!!
(And so on....)
Your list won't be the same as mine and that's OK. However, please make a list even if you keep it only in your head. Just make sure that you can pull it out periodically and look at and add to it. You might be pleasantly surprised at the number of treasures you actually have.
