I had a similar experience out on the creek. My son and I were hammering smallies left and right when this guy

Had my son not been with me I would have cast my crankbait as close as possible to him just to prove a point. If he's going to act like we're not there then I was going to do the same. I was furious! BUT, with my 5 yr old there, there wasn't much I could do without putting my boy in an uncomfortable situation.
