I could never fit in with the thieves in the guild, I had a brutish size you see; really, I couldn't fit in the sewers. Brynjolfs was probably drunk when he thought that I had it in me and I probably too was drunk in believing his words. This idea seems pretty good, gives my freedom more choices in Skyrim. I recall many instances where I wanted to rob someone to make my character's story more depth or something like that.
