Ticking time bomb

Look to the person or persons to your right, now do the same to your left. Do any of those people look like they might murder you. Do any of those people look like a psychotic person about to have a homicidal meltdown. Well it seems that sometimes you can't tell who is capable of inflicting harm on you and your loved ones and in many cases the people that end up doing the most harm are those you know and even close relatives. As in the recent case of an estranged ex-husband who shows up at his ex-wife's family Christmas party and decides to execute people. You know that saying, keep your friends close and your enemies even closer. Just keep in mind your enemy could be thinking the same thing, worst part is you may not even know your their enemy!
