Why people look so much and how to do to p unnoticed on street and in Public?

I'm Man already ped 30 and i dont like to autoyzer but I am well-presented and for example when I walk down the street when I look at people i dont fixed my eyes on them because im a person that likes to respect the others space and because i have education,but sometimes im forced to stare to the others when i notice that people are looking at me staring me in the street.For example if i go out in the street and start facing everybody no one will face me but if i dont face no one the others will face me, strange.For example in the street one person are ascending the street and im descending i look to the person but turn the eyes to not face him or her but that person dont turn her eyes and keep facing me,why dont respect my space ?how to do to p unotice?I dont like to be faced in the street and i walk with my head up because i dont owe anything to anyone.And both men and women look and do not think that normal. how to stop attracting?think the intent of these people is to take me from seriously?Acham q o ataque � a melhor defesa? qo attack is the best defense?
