Staring into space

Waiting for my friend
At the school canteen
Staring at that missing tile
That empty, vacant space
Suddenly a heap of kids ran in but
I just kept on staring; in my own place!
Can't remember what I was thinking of
I guess it must have been kinda boring
Finally as I looked up and came back to myself
I saw a guy with a very red face
Looking at me as if I was looking 
At his groin: which is where my sight
Was pointed as I leaned against
The canteen counter at my back!
It was so embarrassing to think
That he thought I was staring
At his private parts!
I suppose he thought I was a bit weird
To be looking at him like that but 
Honestly: I was just staring into space!
