do you mean wierd from your view or from the view of the doctor??
I've shadowed with a friend before in surgery and it was cool, but the next year I shadowed alone, the whole semester with the same doc. and it was much better....just because you get more attention and experience and you are "forced" to talk with and hang-out with doc.s and staff during meals and stuff....instead of possibly being tempted to just sit with your friend and talk about what you saw or whatever.
