Still Dont Know What Im Doing - Tumblr Posts

So when you start writing one of these, it says "add something, if you'd like". But why? What if I don't want to? The post button is greyed out until I write something, so why does it say "if you'd like"? I think it's an oversight that we should not look into.

While I figure out How To Tumblr, I’ll just post some shit I have saved on my devices

I love these comics 

“Leaving your vessel is not the aswer, stop being a baby!”

I have been procrastinating your requests guys, sorry for that…
