Things I have learned:

Most boys like to be silly..
Older dryers are good to repair, they don't have the new sensors so they dry more stuff before they shut off..
Child proof locks only work for babies.. and some adults. Children are really very quick to figure them out - ask them if you need help.
Babies are very smart and do get bored.
Girls need lots of projects. Boys need activities to keep them out of trouble. If a child is causing problems they are usually available for more tasks and challenges.
Teenagers can be fun to be around! They too are very smart and can get bored... may need attention.
Cars tires don't like screws, nails, and construction areas.
Computers go very slow with cookies on them. Children leave lots of cookies on computers...
6 month to 15 months is a really great time for babies, they can do stuff but haven't really figured out how to cause Big trouble or messes yet!
Obsessive Compulsive kids can be annoying but usually have no clue they are doing it.
Many of the most difficult kids, are brilliant. It is easiest to lead rather than control them.
Spring is terribly Beautiful everywhere!
Life is always changing...
