Claustrophobia n. Fear of small spaces.

Get home from work.
Mail's here.
Letter for you.
You feel your heart sieze up with tension and excitement.
Turn over the envelope, and start to rip it open greedily.
Apprehension overcomes your excited fingers and they start to tremble.
Quick, stuff the letter in your pocket before anyone notices the tell-tale sign of worry.
How long can you put off opening it? Hopefully long enough...
