Someone on a hot day drinks from a water fountain and then goes back to the outdoor activities. During the next break, comes back to the fountain only to find ‘out of order’ signs pasted to the fountain.
If you were this person, what are your feelings? No feelings? Just an inconvenience and head to the next available fountain? Do you think about the cause? Oh, it must be a mechanical issue, or something wrong with the pump?
A particular someone did not consider any of the above possibilities. Instead, he was sure that the authorities shut off the water too late to prevent him from consuming dangerous contaminated water from his earlier drink. But he kept these thoughts to himself. Nothing happened. He did not get physically sick.
However, his friends and family say that he certainly wasn’t the same after this. He didn’t talk as much, and almost lived with kind of an expectation, and seemed to be constantly looking for something. He rarely did anything without reading about it first, did not go to, or use, anything without signs, and usually came home looking dehydrated.
