our fourth aniversary was two months after nick passed. I went to the cemetary with my son and we took a dozen roses. Your mom may not want to do anything but you just leting her know you are there for her will mean a lot to her. Try to make it a happy day, I know it is easier said than done. I love talking about nick with my son, he is only three and I dont want him to ever forget his dad. Maybe take your mom flowers. my prayers are with you and your mom and I am sorry for your loss.
