if you find any twos kissing in the street ( including gays or lesbians) DO NOT EVER staring, do not interfere in anything that is not related to you , keep a distance from your people do not get too much closer, do not touch people even to greeting just simple handshake , wait in a row if you find any people in front of u ( metro, cashier, ATM, etc.. ), do not carry any child or insist to play with him in front of his parents, do not speak with a loud voice in a public places, seat only in the seats specific for you ( keep seats for elders and disabled people empty... follow the signs in transportations)
