"A longer walk"

Dad managed a bit further on a walk and he didn't refuse when I asked him if he wanted to go out. His pace is really slow and he is so out of breath too whilst walking. He settled once home but at tea time shortly after leaving the Carers rang me to come back as he was complaining of not being well. It was just after 5 and I had to tuck him up in bed, hopefully for the night. Will try for a water sample again in the morning. Clutching at straws for an answer to the problems dad is encountering. He was so agitated but seemed glad to get into bed. It's been so cold today what a change from the sunny days of recent weeks.
