From the time Ari was able to shake his head back and forth he’s been saying “no.” But upon reflection, I’ve realized that “No” has meant something different at each age, starting at around two, and now verbally running rampant at four. Each year, “no” has increased with sophistication. Here’s how “no” has evolved:

Age 2: No!
Meaning: I just figured out that I can disagree with you! Now I’m going to do it for fun, all the time!
Age 3: No!
Meaning: Don’t tell me what to do, even though what you’re saying makes perfect sense! I obviously have a better idea!
Age 4: No!
Meaning: Not only do I disagree with you, but I’m going to spend as much time as it takes to get you over to my side. You are clearly mistaken.
Age 32 (Me)
Meaning: I’m right, you’re wrong! The end!
