Beginner Gardening: Is this a weed?, 1 by gawkyswan

Gerbera enthusiasts, I need your help!

I bought a potted Gerbera daisy a few months ago, and it's been surviving pretty well. However, last week when I was in Chicago, I left my Gerbera outside to let the rain take care of it (really not a good move, now that I'm reading that they thrive best in drier conditions) and it was pretty much close to dying.

I moved it into a sunnier spot where the rain can't reach it and found this growing, but is it just a weed? I'm afraid I'm not skillful enough to id the plant by its leaves.
