Superstitious....

Is it bad to erase a date off of the calendar before it has actually passed. I was updating our dry erase board calendar in the kitchen tonight (mainly for my school work because I would be lost without that thing) and wiped all of October off and filled in November. It felt a bit odd doing that - like this day was going to end up badly as I had already erased it. Am I weird (okay well we all know that I have issues) or does anyone else think this too? Someone please say yes.
