What is Usage?
The frustrating event of your significant other monopolizing the use of your possession or property that normally would be yours to use whenever you wish.
When your live in girlfriend uses your personal PC even though there is an extra functional computer in the house. "I had to check my e-mail from the basement PC, due to Rachel usage."
When the husband takes to watching the game on the small kitchen TV over the oven. "I missed out on the soap operas while I was cooking dinner due to Fred usage."
Your jobless and carless boyfriend keeps taking the car. "I'd love to meet you at the restaurant, but can't make it due to Craig usage."
When X uses Y. "I could have done Y, but could not due to X usage."
