1. You spend most of your time trying to take the worst photo of them physically possible.
2. They're definitely not saved in your phone by their real name.
3. One of your favourite games is to see which horrible nicknames they'll reply to.
4. Another great game is to point at ugly things and say "That's you."
5. You'll look after them when they get too drunk, but you'll also tell them everything they said in the morning.
6. And you take every opportunity to tell new people all their embarrassing stories.
Or even just repeat them again. Every day. For the rest of their lives.
Like the time they threw up in the bath all over themselves at their own house party.
