Coal, that is a tragedy of epic proportions. I am sorry for your loss, and especially for the loss that the orphans have sustained.
Like Aries (are you certain Aries, that we are not related?), I have also experienced the feeling that my parents are with us at every family simcha. They have seemingly taken great pains to let us know that, by doing the same thing over and over again at every wedding, bar-mitzvha seuda, vort, etc. A centerpiece (usually flowers) falls over each time, at the precise moment when someone is talking about my parents. The flowers were totally secure, and the centerpieces had been undisturbed, and remained in place until that exact moment when they keeled over, for no apparent cause (no one nearby, etc.). My family is used to this by now, it has happened so many times over the years, B”H.
