For example, if someone asks you about a recent breakup you went through, you might say something like, “It just didn’t work out. ” This is an acceptable response, but doesn’t reveal anything private about you.

For example, “like” others’ posts on Facebook from time to time and post an occasional photo with a brief caption.

Confidence and arrogance are different; don’t be rude and brag about how great you are to everyone.

For example, if you normally never speak up in class, answer a question that the teacher asks one day with a thoughtful, intelligent answer. If you’re being mysterious to get a guy’s interest, you might say something attention-provoking to him before walking away.

For example, if you got into a big fight with your sibling or friend earlier in the day, act as if it’s just a normal, uneventful day. Avoid wearing a frown or crying in front of people you interact with throughout the day. Try to stay calm, cool, and collected at all times. You can also plant a quiet, almost smirking smile on your face when people are talking as if you have some secret inside joke that no one else is aware of.

For example, consider only confiding completely in your mom and your best friend of 5 years.
