Me and my wife were at home on Friday night, when we got a frightening call. Her Gran has been diagnosed with dementia and alzheimer's deceases in the last year, and she had disappeared. We think her Granda may have fell a sleep, and she just got up and walked out. The rain was pouring down, and not the best conditions for a stroll. The alarm was raised when the police found her 80 year old Granda in town with a torch looking for her. My wife and I, all her family, and every police in the town was out looking for her, in every close, shop and street. We managed to find her, on a street she stayed at over 30 years ago, about an hour later. All was well, she got checked out at the hospital and we got her home, and settled. The next night, a one in a million happened. I got home from work, parked up, and an old fella, asked if I could taxi him to a street, about 30 minutes walk away. Well 30 minutes for me. After my surreal evening the night before, I was a little concerned for him. It was late at night, and he had a bag with toilet roll in it. I asked, if he had walked all the way down her to get toilet roll. He said he went out to the shop, and just kept walking. Alarm bells were ringing. I popped him in the van, and drove him up to the street. But he didn't stay there, and then admitted he had been diagnosed with dementia. We got his name out of him and another street, he may stay at, and found him listed in the phone book. After calling his phone number and speaking to his wife, we got him home safe. If the events of Friday night didn't happen, I don't know if I would have realised that this guy may have been in trouble.
