I'm playing a sneak thief/battle mage (joined the Thieves Guild), but have found little challenge in breaking, entering and stealing throughout my progression in the game. For examle, I just did The Sweep Job that required breaking into the Atherton home in Windhelm. I waited until 1:15 am, picked the adept lock and, in sneak mode, broke in. The occupants were still awake (on their way to bed) and I was visible for a couple seconds. Granted I have 75 sneak and was wearing a necklace of sneaking (20% increase) giving me 90 sneak. However, even the best thief would be caught if he/she picked a lock and opened the door to find the occupants a few feet away. The noise alone would alert them. That's just one example. Others B&E's have presented little challenge, spoiling the thrill of nearly getting caught!
Is B&E too easy or am I just too skilled?

This was before the 1.4 patch, so dont know if it would still happen.
