Writer Deborah Mitchell's oldest son, Nick, will be a college freshman this fall. She shared "unofficial commandments" for him to remember on CNN iReport. "I have written both my kids letters over the years, and they've kept them," Mitchell said. "Our memories change as we grow older, so these letters are just a snapshot of what I was thinking and experiencing at the time and the things I wanted them to know."

The writer gives Nick, then 4, a kiss. "My son read the essay, and he said there wasn't anything that he hasn't heard from me 'many times' before. But he was most surprised by the tone. He said it sounded so sad, as if I were losing someone," Mitchell said. "He's not used to me sounding sad, especially since I've been telling him how exciting this will be for him. ... Being a parent is a privilege, and letting go is all part of it."

Mitchell and Nick at 16. After the death of her father last year and realizing that her son's college move-in was just a month away, Mitchell decided she should write a letter to her son. "I think that it's important to say these things before it's too late," Mitchell said. "I would recommend that every parent write a letter, even if he or she just stashes it away. It's very therapeutic.
