Use the force
There are days when I think there should be a law against anyone over the age of 65 using Facebook. I know that might sound harsh, but knowing what you’re actually reposting and sharing with your friends and family involves a small amount of tech-savvy and some knowledge of modern culture.
Case in point: this is not Jesus. I’m glad that Aunty Karen isn’t ashamed to have a picture of Jesus on her wall, but I’m pretty sure she’ll be more than a little embarrassed when someone has to explain to her who Obi Wan is. Also, who Ewan McGregor is.
