Hiding something

Sometimes because of pride or ego or a mistaken idea, one person may not confide in another or tell them the whole truth. Have you ever been in a situation in which you didn’t want the other person to know something about you? You had something you wanted to keep secret? How did you act? Did the other person realize you were hiding something? How did your behavior change the way they acted toward you?

I've always been a person who has kept stuff to herself im not really that opened
with you unless I know you Im a great secret keeper and im very blunt with people
but we all have our hidden stuff my behavior does change but it depends on the secret or
what im hiding like for instance when I was covering for my older sister when she was out
late my mom seen how i dramticaly changed good thing is that she didn't find out.

Although my behavior changed right in front of her with her knowing she could've asked
me why but instead she kept doing what she was doing and my sister owed me big time so
that was a good thing otherwise we both would of got introuble and grounded for life pretty
upsetting
