Question #2: Is your friend also your "friend" on Facebook?
If the answers to both questions are "YES", then most likely your friend's Facebook account has been hacked, and your friend is nowhere near Bangkok. A few of our friends have already fallen or nearly fallen into this trap - the lucky ones tried to call their friend's mobile first, and were surprised to hear that they are in their Thimphu office.
Take a glimpse at any computer screen in Thimphu today, and you will mostly see an open Facebook page. The Facebook craze has definitely swept Bhutan like the rest of the world. Now that everyone has more "friends" that they can remember, hackers have found a way to take advantage of your social network. This same scam has been used with hacked email accounts.
To avoid getting your account hacked, make sure to choose a non-trivial password and keep it private. When you receive a "help me! please send me money" request, even if it appears to be from your cousin's genuine email address, it is best to double-check with your cousin using "low tech" such as a phone call.
