Update - he's his own worst enemy...

[desperance]

Not while Mac's around, he's not...

But honestly: my poor Barry turns out to be easily cowed. Mac chases him, and he gets tree'd - well, windowsill'd - or backed into a corner, and even then he doesn't use superior mass or musclepower, just hisses and flinches back; and then Mac wanders off, and Barry - yup. Barry goes after him. Cringingly. Just can't keep away...

Truly, I'm really surprised; I thought Barry would be the bully dominant one. Simly not. But there is still time, of course. Lots and lots of time. And tomorrow they get to be on their own all day. Yikes!
