Cookie Thief Song... I wrote it at 18

As I sat down in the airport on that rainy day    
I discovered that my flight would be delayed  
So I went up to the stand to grab a book to have on hand    
and I thought that I would buy some cookies too    
   
Who's the cookie thief?    
Is it me is it you?    
Things aren't always just the way that they appear    
Who's the cookie thief?    
Is it me is it you?    
If I look inside the bag I find the truth    
   
I thought the man that I sat by was a friendly one    
so I thought my choice in seating was well done    
I reached into my bag to grab a cook maybe two    
but he thought that he should grab a cookie, too!    
   
At first I thought in my anger I would come undone    
But then I thought what's the harm if he eats one?    
I thought I shouldn't care but my friend still wasn't done    
We ate together til the bag was almost bare    
   
We looked together at the bag with one last cookie    
I just wondered what the man would choose to do    
and then to my surprise he grabbed the bag and reached inside    
He took one half and said "the larger half's for you!"    
   
 I sighed and left with relief as my flight was called    
for at last I was away from that rude man!    
so I sat down in my seat and said "I think now that I'll read."    
...but when I looked into my case guess what I found!?    
   
Oh, it's too late, too late to apologize!    
My cookie bag is in my case I thought with grief    
I see... how can it be!? I was the rude one full of greed    
I was the ingrate... I was the one who was the thief!    
   
   
Who's the cookie thief?    
Is it me is it you?    
Things aren't always just the way that they appear    
Who's the cookie thief?    
Is it me is it you?    
If I look inside the bag I find the truth
