A school corridor is lined with 1000 lockers, all closed. There are
1000 students who are sent down the hall in turn according to the following rules.
The first student opens every locker. The second student closes every second
locker, beginning with the second. The third student changes the state of every
third locker, beginning with the third, closing it if it is open and opening it if
it is shut. ( this happens for all 1000 students )The problem is: Which
lockers remain closed after all the students have marched?

I don't understand why everyone wouldn't use this if it is so reliable and runs indefinitely without electric power? Does anyone have one and tried it? Is it really as quiet as it adverises ( supposedly "silent")

We've been dating for a year now. We are exclusive and all. We have been pondering a future together. She introduces me to her family member as her boyfriend. So far so good, you may say.
But there are some things I still dont get, and make me doubt about what she feels:
- She rarely shows excitement when we meet
- rarely is romantic to me
- is NEVER jealous
- rarely says the things she likes about me
- She's NEVER said "I love you"

I'm not that romantic eithter, and truth be said, I hadnt said ILY first. I thought she was waiting for me to say it , so I said it. She said NOTHING in return. I then I said I wondered why she was never romantic at all, she said "thats the way she I am." "What do you want me to say?" I asked her if she was happy with the relationship, she said yes, that she wouldnt be with me if she wasnt, and that a guy like me is hard to find.
Most of her actions say she cares, but on the other hand she wouldnt say it overtly. Can you give some advice here? Thank

NOT counting the obvious liver and other problems associated with the acetaminophen, as that is another issue all together. i know it is usualy perscribed in 5, 10 and 15 mg tablets. so i guess this is more of a hydrocodone question.

im not trying this or some kind of junkie, just have a hobby of drugs and how they interact with the body. :)
