should & should not

sometimes
people is confusing between should or shouldn't
should i do this, or shouldn't
should i buy this, or shouldn't
should i behave like this, or i shouldn't

sometimes
something should be happened or should not be happened
is without thinking and u will know
should or shouldn't

in my opinion
people should aware
aware the thing happened beside you
aware the people beside you
sometimes
is just don't want to express the feeling
but not we don't have
do not shout out
does not mean that we don't care
everything must be aware yourself

people's patient is limited
don't do something make you regret
