What are some of the ways that you had commemorated your loved one's passing?

Tomorrow, it’ll be 2 years since my Mom passed away. I’ll be busy tomorrow, but, I know that I’ll be thinking about her all day. I’m going to try to think of happy times and not the sad/difficult times near the end. I’ll make my way to the cemetery and leave her some Lilacs (her favourite) and probably sit down by the beach by myself and think about her..
