Should I, shouldn't I?

I've gotta remain ambiguous here, there's a degree of sensitivity involved with the subject matter. There's something I want, and have wanted for awhile now. The only problem is, it kinda "belongs" to someone else, as I've long suspected. I know some of you who insist that as long as I put in the work and earn it, the it can be mine, and I can just picture you egging me on. Then there are my principles. You don't just grab something that belongs to another. Then there are the feelings. I want it. Bad. Maybe even more now than before, as I now know I can't have it. D'oh!!
