Sorry for your loss. I lost my Father twenty years ago and sometimes just a minor thought of something he said or did will pop up in my thoughts. Those are the moments I feel he is still here.
Keep your Mother in your thoughts, think about her everyday...she will always be with you.
piper64, I've been told there's no right way to grieve, and no time table. Do it your way. Re-experiencing some sorrow, even years from now, is your prerogative.
Please accept my condolences on the loss of your mom. Your mother sounds like a wonderful soul that touched the lives of many. No doubt she will be missed. Enjoy your pipe and whatever else gives you comfort in this sad time.
