Halcyon

An all around great person who is always willing to listen and checks in on you. They're an amazing person and be happy if you have them as a friend. Their name shows their uniqueness and individuality. As well as their peacefulness that they hold.

Damn hanging out with Halcyon was so nice. I gotta hangout with them more.

Halcyon

A person who does not care about other’s feelings. She is manipulative, cunning, childish and worst of all tears friends apart from each other. An overall terrible person.

Wow Halcyon is being a really terrible person today.
