Nine times out of ten,
1.You don't get money back when you lend it to family.
2. The person you don't want to hear what you said behind their back hears it
3. The day you call in sick to go to the sales at National Liquidators even though you NEVER do it and probably won't again, is the day that the big boss comes around to inspect.
4. Your children will grow up and do all the things they swore they'd never do when they had children of their own.
There is more. This is just some of what you can count on.
