I don’t know how many times I tried putting their medicine in juice or milk, and they still could taste it and wouldn’t drink it. Same with the elderly. I take care of my elderly aunt, who is 88, and on her last visit to her doctor in April she had a slight bladder infection. Although the medicine smelled like cherries, she would fight it every time she had to drink it, no matter what I put it in to disguise the taste. So, no, this is completely unbelievable that Brady would not have realized that his drink had a different taste and put 2 and 2 together. Oh, well, it’s like mommytutu said, we are over-thinking the illogical minds of the writers.
