Do you think it is a good idea to keep a diary so you can
look at it when you are old? Why? / Why not?​

I personally think it is a good idea because it keeps memories or maybe memories that you don't want to keep so later on you can burn the dairy or rip it. If could be a good dairy or bad one and you can add pictures, drawings, all sorts of things! :)

I think it is a good idea. If you keep your diary you can look back to it in 10-20 or more years. It will be back memories good and bad (hopefully there’s more good then bad). With the diary you can use it to make story’s or just to look back at. Sorry if this doesn’t make sense. Have a great day! :)
