Do you know how sometimes we visit graveyards to say hi to our loved ones who have left us and we leave flowers or cards for them? Well, some people like to visit graveyards not to see their loved ones but to see the graves of famous people or learn about history. They are called "tombstone tourists" because they are like tourists who visit different places, but they just go to graveyards. They like to read the names and dates on the gravestones and find out more about the people who are buried there. It's like a way to learn about the past and remember people who have made a big impact on the world even though they are not here anymore. It's important to be respectful when visiting graveyards and not disturb the peace of those who have passed away.
