Well for me it's hard i have OCD (really) I am a door checker i have to check my door several times before i go to bed to make sure it's locked and if i can't remember i have to get out of bed and check it again. I'm also obsessed with bad food i won't eat chips after the first day opened i won't eat anything in the fridge that has been there for a while ( cheese) I'm compulsive about expiration dates i have to get the furthest expiration date possible and consume the food fast also i won't drink or eat off of anything someone else has even my own kids if someone takes a sip out of my drink i tell them to take it or i throw it away. OMG i sound so horrible!! There are a ton of other things i'm obsessed with but thats enough for now LOL don't want you all to know how weird i am just yet
