Stupid allergies

I was looking at him looking at her,
Anyone could see he liked her,
Then I could feel it,
My lip was trembling,
My eyes were watering,
My throat was burning,
I made that sound you make when you're holding back tears
Now he was looking at me,
I coughed and said the only thing I could,
Stupid allergies.

My friends made me post this. Trust me, it wasn't my idea.
