Were the Indians friendly when Columbus arrived in western hemisphere?

Of course! The Native Americans were friendly when they met Columbus and the Spanish explorers because they thought Columbus and his explorers to be honorable people. Columbus portrayed himself in this way. He was very kind and polite to the Native Americans and made sure to treat them with respect. The Native Americans, after all, had never seen Europeans before, and although they were a bit taken aback, they admired them (of course, until they realized the Europeans only wanted their land and were only seeking to exploit them).
