Should we celebrate peoples birthdays after they are dead

I think we should celebrate peoples birthday because when someone in your family passed away you should remember them and when it is there birthday you should remember them by thinking that they have come back and playing with them sharing food with them i am going to argue about if you don't think you celebrate peoples birthday when they are dead. In Mexico they have a big celebration called the Day of the dead and in that celebration some people believe that the people who have died there spirits come down and they have a party. They have a big party to celebrate that persons life. People celebrate outside and they dress up like ghosts and skeletons it sounds scary but it isn't scary at all. They dance and sing all kinds of songs.
