Memories can be triggered at any time and if you’ve recently lost someone, you may want to know how to keep memories alive. After losing my dad, sometimes a song on the radio makes tears fill my eyes, and other times, I’ll see or smell something and a previously forgotten memory will pop into my head. These “new” memories are like gifts, and four years after my dad has been gone, sometimes they even make me smile instead of cry (though not very often).
