Why are you scared to do it, MB? Are you afraid they will think you are incompetent? If they are supposed to be mentors, they are there to help you! I understand it, though. I ask for help all the time at work (my job is complicated and I am somewhat new, and still learning). I used to be afraid to do it, but I now realize no one expects me to know everything, and they appreciate being asked, because it means I'm trying to learn and get better at the job. It is in everyone's best interest that you learn everything you can!
