The actual funeral lasts between 1 and 2 hours. This one sounds very sad, like a car accident. So it will probably last the whole 2 hours, with speeches and stuff. The wake is usually held right after, at someone's house. Everyone brings food.
I just have a small bag that I store all my diabetic stuff in - needles glucose monitoring equipment and insulin. You can leave your insulin (that you using) for 4 weeks out of the refrigerator, but if you are storing your insulin that you aren't using it should be kept cold and in the fridge. I was always told that you had to keep it refrigerated, but my diabetic nurse said it'll probably sting and oh boy was she right.
A bottle is supposed to be fresh for 28 days after you take it out of the fridge and start using it. As long as it wasn't in direct sunlight you should be okay. Cold insulin kind of hurts when you inject it-I never store mine in the fridge except the bottles I haven't opened yet.
