Did I Spell "Doubt" Correctly?

I had a moment of great doubt this morning just before dropping my mail into the mailbox, wondering to myself:

What if I realize an error in my credit card payment after releasing it into the mailslot? Did I remember to write my account number on the check? Would I actually have the personal fortitude to wait here until the pickup time posted on the box (4:17 pm on Weekdays, 11:04 am on Saturdays)? Does the Mailperson even come at that time? Should I get here early in case my watch is slow? If I am here at the mailbox when the Mailperson arrived, would he/she believe me and give me back my mail so that I could properly write my account number on my check? And if I got my mail back, would I quickly tear open the envelope only to realize that I actually did write my account number on the check absent-mindedly while I was thinking of something else? What was I thinking about?

Was my mind on the garbage I had thrown in the dumpster moments before? Was anything in there important? Did I accidentally throw out that $25 gift card to Petco? If not, then where on earth did I put it? Should I stand by the dumpster and wait for the Garbageperson to empty the dumpster? If I did, would he/she believe me and give me back my garbage? Would I even recognize my garbage from all the other garbage in the dumpster? Perhaps the Garbageperson would help me root through the garbage and find my displaced gift card if I agreed to split the gift card with him/her? Would he/she really have need for a gift card to Petco? Garbagepersons have pets, right? Or is that a stereotype? Do I want to risk offending a Garbageperson by asking? Would he/she then want the gift card for himself/herself? But if he/she doesn't have pets, the gift card to Petco would be useless to him/her, so what do I have to lose by asking? What can I get with a $25 gift card from Petco anyway? Would it really be worth the bother?

Oh, wait, didn't I spend that gift card last week on a scratching post, two squeaky mice and 40 pounds of kitty litter? But what about the two squeaky mice that squeak slightly out of tune with one another? Should I take one of them back? Can you take back just one squeaky mouse? Will I need my receipt? What if I can't find the receipt? Where is the receipt anyway? Shit, that's right...I threw it out.
