Wow 7 people voted "Can't think of anything to say." I have the same problem. Wonder why its so common. I feel like part of the problem is I have no casual go to figures of speech or clever metaphors or anything. Like I do have things to say sometimes but am at a loss as to how to express it in a straight forward and interesting way.
You live up in your head
Scared of every little noise
Someone's always breaking in accidentally
Using nothing but their voice
