Heh, the title pretty much says it all. Basically, when I logged in last night I had to pay attention to the group's battle, down-time chat in the group, while simultaneously handling 3 other conversations in direct tells. Oh, and don't forget keeping an eye on the guildchat and attempting to also read the /ooc and /shout channel. In fact, once I did /random 100 when the other group near us was rolling because I thought I had missed the call to roll on some item drop (sighs, Solarflare didn't make too much fun of me for that). Then there was the random tells asking me to join a group, or "can you experience rez?" tells (I was the only cleric in Frontier Mountains last night).
So if you ever wonder why I'm taking a bit of time to get back to a tell, or asking "um, what were we talking about?", it's probably because I'm trying to juggle too many indepth conversations.
