Canceled vs. Cancelled

I vow, from this day forward, to never spell the past tense of cancel as "cancelled."

Why? Because if the past tense of travel is "traveled" then the past tense of cancel is most certainly "canceled." I don't care if the dictionary claims both are right. There are enough exceptions to English language already. I refuse to perpetuate yet another!

(If you think this has been bothering me for quite some time now, you are right on the money)

OCD? maybe...
