Hello. I'm a 56 years old and I'm a bit new to the internet. On Facebook, my grandchild told me trough our chat about how great these things called memes are but I don't know what memes are. He said they're everything to him, talking as though memes were deities and told me to come to a "meme temple" that he mentioned to be also known as "s4s" in 4chan.org. So here I am. I would like to learn about memes and what they are. Please help an old guy understand more about the internet. Thank you!

PS I don't know what to use as image for this post so I'll use my Facebook profile picture so you can find me ONLINE and we can get in touch. Thank you sincerely.
