Real life happens, and as unreasonable as it seems, it even happens when we're gaming. The phone rings, a parent needs you to take the garbage out, a child gets out of bed for a drink of water, the cat wants out and in and out again, the spouse needs help
carrying something in. That kind of thing takes precedence over a game -- we all (should) know that. When it happens, you afk to take care of it.
Chances are that this has happened to you, and you returned from afk to find that your group has raced ahead without waiting, leaving you to catch up as best you can. We've all been there, so what are your feelings on it? Are you okay with being the straggler trying to find the group if you are called afk or have to stop to sort inventory, or do you prefer the "stay with the group" approach?
