You know you are obsessed with Percy Jackson when:

Someone close to you dies and you give them money just in case

You go on a cruise and you hope that the boat isn't the Princesse Andromeda

You are on a boat and you hope that Poseidon is in a good mood 

You are in the air (flying, cliff-diving, hang gliding, etc) and you hope that Zeus is in a good mood and won't blast you out of air
