Has anyone heard of Fu Dorje Sherpa? He was the forth Nepal-born to climb Mt. Everest but was the first one not to accept offer from Indian government to have Indian citizenship. In fact, he was the first one who was really proud to be Nepali.
Citizenship may be a choice but the pride of the flag is truly internal feelings. Whatever reasons other previous climbers had to choose different nationality, Fu Dorje didn't relent to their offers. I salute this great man for holding Nepalese soil despite of temptations from other governments.
