How someone reacts to a playful joke can clue people in on this person's true colors. This man learned this lesson the hard way.
"This happened to a friend. He woke up really early one morning because of middle age. So while he makes coffee, he checks the lottery numbers and he didn't get a single number. Realizes he needs milk for the coffee and runs to the corner store. Starts to buy lottery tickets for the next drawing, and comes up with what should have been a funny idea. He buys another ticket and plays the numbers that had already won the night before.
He goes home and puts the ticket on the fridge where the other ones were thinking she will have no reason to pay attention to the day they are for. An hour later, his wife gets up and makes some coffee and he yells from the living room that he hasn't checked the lottery numbers yet and for her to see if they won anything last night. He hears her use the laptop to check the numbers and then she is quiet for a minute. He said he had this big grin on his face waiting for her to start yelling they won and thinking how funny it would be (I actually think fake winning lottery tickets, and the prank he was pulling, are mean, but that is beside the point).
She yells from the kitchen that they didn't win anything. She heads back upstairs and 15 minutes later she comes through the living room with both their elementary-age kids in tow and says she forgot to tell him she had to go to her moms for the day and was taking the kids and just leaves.
He was shocked. Went and checked, the lottery ticket is gone, not in trash or anywhere else. He realizes she thinks they won the lottery and she is trying to run off with the winnings.
She won't return calls or talk to him and when he calls the house the grandma will confirm she is there, puts the kids on the phone, but that is it. She finally shows up with the kids a couple days later and just walks in the house and says 'Forget You!' and walks into her bedroom and won't talk to him!
Kids confirm that mom thought she had won a ton of money. Realizing what kind of person she is, and that she also isn't very smart to think she would have gotten away with it, he divorced her. Probably not a ridiculous reason to divorce someone, but ridiculous behavior that would cause you to divorce someone."
