My First Travel Mistake.

I hadn't even left yet.  It was the night before.  I decided to visit my online banking quickly to make sure everything was in order and all of my automatic withdrawals were set up while I was away.  That's when I notice a charge on my Visa.  A charge of $162 from a hostel in Greece.  "Why are they charging me!? I haven't even stayed there yet! I put a deposit down, that is all!" are the thoughts racing through my mind.  I go online to Hostelworld, where I check my booking information.  At that time, I see a notice saying that my failure to show up for my reservation resulted in a penalty charge.  "EXCUSE ME!?" Now I am hot and rage-y, I am ready to fire off a very rude e-mail telling them they are a month early, but that's when I see it.  I had somehow managed to book the 7th month instead of the 8th.  CURSE YOU MATH! I have always been terrible with numbers, and now it cost me $160.  Anyway, as per usual, I found my silver lining and was able to re-book hostels in a different way that allows me more flexibility and a couple extra days island hopping instead of in Athens, like a mulligan of sorts.  This time however, I was very careful to select the correct month.
