This little old lady who lives next door made me some egg salad for lunch. I don’t dare eat it, she poisoned it! I know she did!
Why would she poison your food? Did you take out an life insurance policy on yourself in her name and she want’s to collect on it? Are you a threat to her physically and she must defend herself? Or do you believe she is just a psychopath and wants to poison everyone with her egg salad sandwiches? What exactly is her motive here?
