This just happend to me the other day.. 2 does and a fawn come running in front of mt Step dad and I about 130 yards away in a clear cut we had had some luck the day before. I clearly saw which doe was the mama and the fawn was right at her side the whole time. So we made a stock to try and see if i coud get a shot at the other doe . i knew where they were but had lost sight of them in the thick brush when all of a sudden i found my self 30 yards away from a doe so I drew back put the pin on her and looked as much as I could for the fawn Hoping it wasnt mama and i just glanced too long and the deer hopped away...wasnt the mama either

But had i just shot that doe carelessly and it was the mama my uncle and dad would have seen it and they even said DONT SHOT THE MAMA OR THE FAWN ...So instead of dwelling on the fact i didnt shoot the deer actually felt more like i made the mature decision of not being sure and waiting a few seconds to see if it was the right doe to shoot
