The other day, I lost it on my daughter. She had taken out a school library book for the third time and, for the third time, she’d completely and utterly forgotten where she could have possibly put it.The first time my six-year-old lost a library book, I was a good mom. I explained to her the importance of taking responsibility for her things, particularly things on loan. I reminded her of the designated spot in her room where the library books lived when she wasn’t reading them (this spot is not on her bookcase mixed in with the hundred books or so that she and her sister own). I found the book, buried in a toy box, and told her that I would pay the fine but that she had to help me Swiffer the kitchen floor to earn back some of the $5 fee.The second time, I was calm—albeit a little less so. Again, I pointed out the spot where she should keep the book when she was done reading it. This time, rather than dole out a chore, I took away a toy that was the amount of the fee and, since I couldn’t find the book, bought back the book that she’d lost at a store and had her bring it in.The third time, I yelled and nagged. I slammed my hand down on the desk in her room where she was supposed to keep her library books and asked her why in the heck she couldn’t remember to put them there. I told her that money didn’t grow on trees (horrible both because it’s a cliché and because it means I’m turning into my own parents) and that we had paid thirty dollars in fines in the past three months, also known as the cost of takeout dinner for our family of four. I threatened to have her write a note to her teacher explaining that she was not allowed anymore library books because nothing her mommy did could help her remember to be responsible. On and on I went, until she cried. It was not a good day for either of us.Afterward, I felt very guilty. She’s six. She forgets things. It’s developmental. It’s also an accident. She’s not trying to get me to buy the book by hiding it. To be completely honest, if she left the book in the kitchen while I was cleaning, I might have tucked it away somewhere and forgotten about it.I also had learned something I can apply to my villains. Sometimes a villain doesn’t start out bad. They try to do the right thing and it doesn’t work. Then, they try again and it doesn’t work. Ultimately because of a lack of patience, inability to deal with frustration or some other moral flaw, they lose it and opt to do something negative in order to achieve a desired result. Yelling at my kid is bad. By the end of my tirade, I’m sure that she no more remembered where to put the book than she had the first time I’d shown her the special spot on her desk. All she was thinking about was that mommy had made her feel horrible. But, I was frustrated and annoyed that doing the patient parent thing wasn’t helping and I got angry. I became the villain.Clearly, I still feel guilty about my behavior because I’m blogging about it. But at least I can bring the insight to bear on my writing.
