I just ate a pistachio shell

I thought I was supposed to because I bought this little bag of bbq flavored mixed nuts (including corn nuts) and the pistachios were in it and they were unpeeled.

And since I'm in another country I thought, "hey maybe you just eat them in Spain?" The answer is a heavy "no." It was extremely crunchy and hard the whole way down, just like in the states. I would have spit it out if I wasn't sitting on a train.

Common sense told me "don't do it" but I tried it anyway. It's just another example of subconsciously becoming open minded when you're traveling in a foreign country.
