Should I feel guilty? If so, how guilty?

So here's the situation. The supervisor of a different Division asked me to help her out yesterday, building a form. She was worried my boss would be unhappy about me working on someone else's stuff, so asked him if it was okay. His response--and that of a co-worker within my Division--was that is was fine, and long as the supervisor brought them cookies.

Which she did, today. A dozen cookies for each of them. Luscious, crumbly, chocolate chip oatmeal cookies.

Neither my boss nor the co-worker are in the office today. They won't be back tomorrow, either.

The cookies are completely undefended.


So how guilty should I feel for preventing one cookie from potentially getting stale before the recipient returns?!? I mean, really, it's because of my labors that they got the cookies at all, right? I'm sure they would have shared, really!

And, yes, it's a moot point--I already ate the cookie. :devil:

Delectable. She's an excellent cook. Just a little touch of cinnamon.

Oh, they'll notice. As if me stealing a cookie wasn't bad enough, the Division Chief saw them, and he took one too.
