Do they migrate?

I was having a discussion today with a friend about food and if it can move on it's own. I'm not talking Sci-Fi (insert Twilight Zone music here) type of moving. No floating or disappearing food. I'm talking about food actually moving. Either sliding, crawling or walking. Not sure how it's done, but I have proof that it DOES happen! Here's how I know:

When Jay and I got married we had 2nd hand furniture either purchased at a Goodwill store, flea market, thrift shop, garage sale or handed down from family. We appreciated what we had, but we both longed for the days when we would have nice furniture. We decided to wait until our kids were older, so I would have a nervous breakdown if something was spilled by a toddler...which you know would happen.

Fast forward another 17 yrs and we finally got around to buying new furniture for the living room. New sofa, chair, ottomon, 2 end tables & a tv stand. We love it and are really enjoying it. However, the arrival of the new furniture implemented a new house rule.....

NO EATING OR DRINKING WHILE SITTING ON THE FURNITURE (water is acceptable).

It took a little bit of time, but the kids got the hang of it. We have large throw pillows so their boney little butts don't have to sit on the hard wood floor (I'm not a total meanie). I think they like the rule actually. We even heard Chelsea tell her boyfriend "Uh unless you want to see my moms head come flying off, you better sit on the floor with that pizza." LOL So all has gone really well. But...

There is a problem. Every time I vacuum, I notice there are crumbs or pieces of cereal between the sofa cusions or on the sides of the chair cushion. My children look at me with angelic faces and say "No mom, we know the rules and we don't eat anything while sitting on the furniture."

So, I have come to the realization that food travels...migrates. It can fall off a plate on to the floor. Then it travels up the side of the furniture and goes inbetween the cushions. That has to be how it gets there, because no one here would ever lie to their mom...would they? Nah!

Tsk. Tsk. Tsk. Naughty food.
