As a grown man you are, same age as me, you know this does not work as you relate. I'm pretty sure that you've been in similar situations. I've been in several ones. Try to remember some project you've been working on with other people on the past, and try to remember how that project just faded away due to the lack of work or interest of your mates, being you the only one who was pushing the whole thing 100%. That's exhaustig.
Now, imagine that Mark has been in that situation for years and he's now just tired. Ok, you can say that he can come back to LA to work, but... guess what: who ran out back in the day when the rest of the band was 100% commited to the project? Tom, not Mark. Now, imagine that they get together, and Tom starts (or better said: keeps on) messing with AvA and mixing time working with blin and AvA, not being 100% commited to blink. I would be pissed SO much.
Ok, I know that the attitude they just have right now doesnt' make things better, but you know...
Fuck, they cancelled a lot of things just by one person. Is fair to say that Mark, maybe, is just being protective wth his own enviroment right now.
Or we just don't know what the hell is going on n the background right now.
