Karen is one of the best friends you could have, she's always easy to make happy with some stupid jokes or even some food (hamburgers or coffee). She's always down to chitchat or to gossip with her friends about any topic. Sometimes she can be very sentimental but you can cheer her up pretty easily. If you are up to help her, she'll be up to help you too. She usually knows when something is wrong, so you should listen to them more frequently.
