Non Responsive

Gramps, pops his eyes open every once and awhile....but doesn't seem to be responsive any longer. This went on the entire day until.

5pm: On my way home Joel and I (Megan) stopped by to say Hi. Gramps popped his eyes open and said HI to Joel and gave him his normal greeting, like there was nothing wrong with him. It was unbelievable, then his eyes started closing and he was asleep again.
