About a month ago, I left for work in the morning and noticed that at night someone (or something) had placed a large chocolate chip cookie on the front doorstep of our home --it seemed placed (not thrown) because it was actually touching the door. The front gate was not locked, so figured it was either left by a wandering drunk vagrant who had decided to take rest on our doorstep during his nighttime travels, or perhaps had been placed there by an animal (though that seemed unlikely, since no part of it had been eaten). Weirded me out enough that I took note of it, but other than that, pretty much forgot about it.
This morning I woke up to find a large loaf of unsliced bakery bread (a little smaller than a football) on our back porch steps. This really weirded me out, because our gate was locked this time, and our house is surrounded on all sides by a 6-foot fence. Was way too big to have been carried by a squirrel/cat, showed no signs of having been bitten, nibbled or clawed. Nor, given the way porch is situated, could it have been tossed there from street or alley. Which means, some time between midnight (when we got home and entered via the back) and 8:15 a.m. (when I noticed it), someone climbed our fence, placed this strange loaf of bread on our steps, and departed.
Obviously, that’s a little disconcerting. Tried googling, and found this reddit thread (http://www.reddit.com/r/needadvice/comments/2qm1kh/does_anyone_know_what_leaving_bread_by_someones/) by someone who had experienced a similar thing, but which provided no further explanation. Suppose next step is to install some hidden cameras, but was wondering if anyone in the neighborhood has experienced a similar thing or had ideas as to what this might be. Little freaked out right now, would appreciate any alternative explanations that don’t involve a person climbing our fence in the middle of the night to leave some weirdness on our steps.
