I would say stop shadowing, and find something new and more unique that you could talk about. When I went to interviews, people would ask me what I did over the summer. I would start out listing things like being a teacher, a dental assistant.. and then I would sheepishly say that I was also a server at a restaurant. When I would bring up things like that, interviewers would literally tell me that that experience is arguably the most important of what I had listed, and if you've ever worked in a restaurant or some retail gig, you'd understand how that makes a lot of sense. !
