I am sorry for your families loss. It is painful for us when those we love move on from this physical realm. It is important for them to understand this seperation is only temporary and though it seems like forever it really goes so fast. I like to see it as I have extra champions in heaven. I talk to my loved ones often, we laugh and joke and tell funny stories about them in my house, sometimes I hear them laugh with us or their responses. My children especially find comfort in this.
Remember: This life is only temporary so make the most of it
