1. Best,
    My go to for work/formal emails
  2. Thanks,
    I say this even when I'm the one who did the good thing, so I'm not sure why I use it. Perhaps because I want everyone to like me?
  3. Love,
    I often use this with friends, because I think we should tell each other we love each other more often. I do this even when my friend has never said they loved me. Just to get things moving.
  4. - Igor
    I hate you
  5. Целую!
    This is how you say "kisses" in Russian, and it's how I sign emails to my mom.
  6. Give me a break,
    I've never used this, but would like to soon.
