My condolences, but you are certainly in the right frame of mind regarding her always finding a way to be with you.
About 6 years ago my wife lost her dad at too early of an age of 64 after a 10 year battle with cancer. Transcendence and grace filled that house the day Mike drew his last, and he has been "checking in" on us ever since. In addition to sparing my mother in law having to witness him pass (he waited until she was out of the room) we experience PERFECT clear weather in Ireland when we went to scatter his ashes during a time of year that is usually quite wet. Actually it rained the day before we got there and the day we got back on the plane, and seemed to rain everywhere on the Isle were we weren't.
On top of that, my wife left her camera full of pictures on top of he car after a pit stop, and we drove off with it on the roof

We had gone no less than 5 miles through twisty Irish backroads before realized it. We backtracked and stopped when my wife got a "feeling". There in the high grass of the road was her battered camera. It was toast, but the memory card was fine. When her dad was alive, he often joked about taking lots of pictures while in Ireland because it was way cheaper than making trips over there (he and my mother in law visited 4 times when he was alive). He no doubt helped make sure we found our "memories".
There have been all kinds of times where I just know Mike was with us. My favorite was the day we brought my daughter home from the hospital after her birth. Even during the hottest part of July without a drop of rain a gorgeous double rainbow painted the sky as we drove home. We tell our daughter about it all the time. Grandpa's birthday gift.
I don't mean to be longwinded, but I do hope you continue to notice all the wonderful ways your loved ones will touch your lives even years after they have passed on. Keep your eyes and mind open, and she'll always be there. I have no need to tell you that a grandmother's love is eternal
