You know with having social media like facebook, tumblr, twitter, etc… there is a whole new level of social behavior the comes with it, and one that i see the most is when someone freaks out about someone else commenting/liking a very old post or picture or something.
NEWS FLASH: the websites were designed so that people could read or look at old posts and stuff on your page. If that were not the case then content such as your posts and pictures would be automatically deleted after a month or so, but thats just not how it works.
So all i have to say is this: dont think its wierd when somone likes or comments on a really old picture or post, you put it up and left it up for people to look at. If you dont want people to look at and like and comment on old photos/posts, delete them yourself.
But really, who is gonna do that? So dont complain or make someone out to be wierd when they just decided to see your posts and pictures that YOU put on your page.
Have a nice day everyone :)
