Note to self

In an attempt to avoid repeating my own mistakes, I'm writing a little note to myself:
Dear Self,
The next time your family has a super fun, magnet kit in the house follow these directions, or risk havoc. Immediately locate the packet of "iron filings" and discard them, preferably hidden under old coffee grinds. Keeping them will only lead to misery. If by chance, the kiddos find these before you do, you must act quickly. Rather than exploring the wonderful world of magnets with them, yell at the kids to stop what they're doing. Send them into the bathroom to wash the black stains off. While they're cleaning up, gather up as many filings as the magnets will hold. Don't even try to get the filings off of the magnets. It will only lead to frustration and nasty black stains on your fingers and nails. When you've accomplished all you can with the magnets, use paper towel to gather up all the loose filings you can. Throw it away immediately. Otherwise one of the kids will pick it up and run across the room, freeing all of the iron filings. To get the filings off the hardwood, do not rub with wet paper towel. This will lead to yucky black marks. Instead, use clay to pat at them. Then wash the floor to get rid of the clay residue. Vow never to allow iron filings in the house again.
