WAH~!! My large had serious drama on sendout day! I worked so hard to fix the mechanism that broke, but I didn't get it done before the post office closed! It's in the mail today, at least, but still a day late. v_v;; I didn't quite manage to fix it properly, either, so I had to improvise and do something different, which was kind of disappointing.
Oh dear, that sounds like you must've been one step away from a breakdown! It's never worth risking your mental health to get a package in the mail on time! Glad you had fun in the end, though.
