Hi okay when i wave to him first he usually just waves back. Sometimes he wave with fingers and other times he just waves with a hand. but yesterday i saw him walking straight i did not wave to him until he was closer. i wave but i guess he did not see me. but a few secs later he look back for a quick sec and i tired to wave but he did not response. sometimes he waves first to me. what could this mean and we are both males
