How much does happiness cost?

Now, normally I would say you can't put a price on happiness, but in this case we got a whole bunch of it for only $5.00 at a garage sale. It came in the form of this little tricycle.

He calls it his bike and he loves it.
He's really good at the steering, but we need to work on pedaling. Going downhill is fine, but he needs some pushing going up the inclines.

Happiness for Clara these days is sucking on her hands, which is free.
