The last 24 hours

So it has been hectic here. Mum called last night, distressed, to let me know Dad had collapsed and the ambulance was to take him to hospital. We got to Emergency just after 9pm - the same time as the ambulance. After a 45 minute wait (and we had to ask what was happening) we were told we could go through to the room.
They weren't sure whether it had anything to do with operation yesterday or not. They were thinking maybe an infection in the blood stream.
So we left around 11pm, knowing that Dad was to be admitted for observation.
Drove Mum home and got home and in bed by 12am.
Today I spent the day at school - busy, busy, busy. Wet day timetables at both recess and lunch - so extra duty! Got home, called Mum and found out that Dad has a heart murmur and needs more tests, probably to be done on Monday. We went to visit him tonight, he seems ok, but frustrated that he has to stay in hopsital. I think he is also frustrated that it is something else to do with his heart, since he has lost soooo much weight and exercises daily. I must say I have frustrated enough for him it's just not fair!
