Well let's see. I get hit with strollers pretty much every trip. Do I sue? No, because it hits my ankle, the people apologize, and life goes on. I have never been hit with one of the plastic swords, so it probably would not do much damage. The selfie sticks are usually made of metal, and since they are being held up, will contact my head area if they hit me with it, possibly causing a serious injury. A totally different circumstance. And again, I reiterate that most (not all) of the people using them are self-indulged young people who couldn't care less about your personal space, or even hitting you in the head. I mean, why are they taking a selfie anyway???? You really are grasping now, aren't you?
