1. Ask nicely
    Otherwise, you're being shitty
  2. Remember that the person you're asking isn't obligated to do the favor for you.
    That kind of thinking will make you look like a fucking asshole
  3. Make sure to say thank you
    If you don't, you're a complete cunt
  4. Keep your eyes peeled for something nice you could do in return, even if that person hasn't specifically requested anything
    That way, you won't seem like a selfish fuck
  5. Don't only contact the person when you need another favor
    That's really fucking gross
