Two words: TAX DAY.
Stupid me, I forgot to bring my sketchbook before going to the post office. Because what I thought would be a short, couple minute trip turned into an hour and a half wait. Luckily the lady in front of me lent me her pen and there's umm..."writing material" on hand.
Thank you, kind lady and thanks NYC post office, without you this (insert adjective) visit wouldn't be possible.
