Run both the 7min and 4min hourglasses simultaneously. When the 4min hourglass is empty, turn it over so another 4 minutes is run. Meanwhile, when the 7min hourglass runs empty, turn this over too. you will achieve 8 minutes from running the 4min hourglass twice and at the end of this you would have 1 minute on the 7min hourglass. Turn 7min hourglass upside down to get a minute. There you have 9 minutes stopwatch with a 4min and a 7min hourglass.

If friendship was synonymous with love then there would not be 2 words to describe one idea. LOVE is the emotion you feel for someone/something so strongly that you want to protect them with your life. Friendship, on the other hand, makes you want to sacrifice for someone who would make the same sacrifice for you. Love is usually based on sexual desire. LOVE and FRIENDSHIP both are not based on nationality, creed, religion etc.
