Method to make your tenant's day miserable

1. Tenant ask about possibility of having a cat.
2. Landlord says yes, you can have a cat.
3. Tenant lets landlord know when they can expect a call from SPCA.
4. Landlord says it's all good.
5. Tenant goes to SPCA, fills out paperwork. SPCA worker calls landlord for confirmation.
6. Landlord says yes to SPCA worker, hangs up.
7. Landlord immediately calls the tenant, informing the tenant that she will need the house back in about 5 months or so. Don't worry, you have plenty of time to find a place to live.

I = tenant

Would've been nice to know just a few minutes before I get the cat, wouldn't it?
