Runescape is very different than real life (obviously). In runescape, you will find that whatever you say will not be taken seriously at first. If you ask someone to be your runescape friend, they might assume youre a moocher and only talking because youre after their runescape items.
But having a network of friends in runescape is part of the game. Somehow training is less boring, fighting runescape dragons is less scary and PKing is ten times as fun whenever you have runescape friends nearby keeping company in runescape. But making a runescape friend in runeScape is very different than making one in real life.
One of the best ways to make a good, lasting runescape friend in runescape is PKing. If you like to PK then find someone in runescape around your level. Ask them to team up (make sure they dont backstab you!) and after you get your first kill together youll have a Runescape friend for life in runescape.
Another thing: if youre selling an item to a runescape player and its a fair price (it should be), then dont hesitate to chat about stuff outside of the trade about runescape. You might find that youll make a lasting runescape friend this way not to...
