You were invited to two parties but they will happen at the same time! At party 1 your favorite band is playing and the other one is your best friend's birthday party.
Where should you go? No worries - you are a time travel agent in training. You can go to both parties! To quickly switch between both events, check out the last commits and
create branches with the `git branch [string]` command. Now you can easily switch between both branches by calling `git checkout [branch]`.
