Haha simple question and has simple answer,
Girls think boys are suspicious, and ask boys they will tell Girls are suspicious,
and more over think again, Men changed for women, but women can't or never change for a men, simple because, women go by what other women think of their men, but men go by what their women think, so it is ultimately men do what other men think,
Simple example, Men have consumed the proposal of a working women, but can a Women digest non-working men ????? think deeply you will find at certain point of time there is nothing called suspiciousness, you will be suspicious only in case were you find it hard to believe he did that, but when you just let him do what he likes, then there is nothing called suspicious in this, say you are suspicious that he speaks to other women, but if you in first place don't have any objection to him speaking to other women then there is no question of suspiciousness, right, this applies to both the variety of human being, girl as well as boy,
