Being a Twitter user you know that to talk directly to someone you simply put an @ symbol in front of their name. Perhaps what you didn’t know is that Twitter guesses and if you do not use the persons FULL username not only may your message never get to the intended person but it will also go to any other user with a similar name. For example my username is dani so when people want to talk to me they need to use @dani however I will also receive messages to anything similar to my name such as @Dani or @dani monkeytoes. So if you were actually trying to talk to danimonkeytoes and you put a space between dani and monkeytoes the tweet will come to me too. So be sure to use the correct and complete username when you are trying to @ reply to someone otherwise someone else might get your message too!
