Yes, fighting is always going to be a part of friendship. I've realized that I actually know very little about the friends that I don't fight with, so arguing with people comes with knowing them well, I guess. But there comes a time when too much fighting is, well, just too much. Like I said somewhere before, it would be like those girls at school who are constantly fighting over nothing. They say they'll never talk to each other again, but the next day, they're friends again. Then they argue some more, and the cycle repeats itself. And those two girls never even have a moment of friendship. It makes you wonder how they even became friends. But Mac and Bloo haven't gone that far yet. So nevermind.

Mac still is friends with Wilt, Coco, Eduardo, Goo, & probally the rest of then house. He could just ignore Bloo & still come there.

Despite all of Bloo's shortcomings, I honestly CANNOT see Mac IGNORING Bloo and coming to Foster's just to see the others. After all, any other kid would have left Bloo long ago (more then likely) because he can be more than difficult when dealing with him.
If anything, Mac would maybe try to end the friendship and move on, trying his best to keep Bloo from getting too upset about it.

Honestly though, none of these theories work well, I don't get any kind of sense that any such thing would happen.
I can see them being like Herriman/Madame Foster in so many ways, and nothing else seems to fit. :):bloogrin

Mac and Bloo will be best friends forever and ever and that's all there is to it. Kageri has spoken!

Even when they're dead.:)

True, but that would defeat the whole purpose of the series and why he goes to the house in the first place. Yes, he is friends with everyone else, but the reason he keeps going there day after day is because of Bloo. If it wasn't for Bloo, he wouldn't go there nearly as often (or so I think).

Again, while they fight quite a bit, I honestly can't see them ever ending their friendship. It would just seem so....pointless.

Mac is only cool because he imagined bloo

Hey, I think Mac's cool on his own too....

Darn right! Mac's a great character all by himself, but he really does work better when he's with Bloo since they both enhance the other's personalities and actions.

I beg to differ. :macwor:
