COW !
"Nothing Sucks Forever"( hattip MesaMan), but since this is bovine territory and realness abounds, sure other things can and do suck and at times take turns sucking and they can suck real good. But like you said ( and Robby) the trick is to figure out how to deal with that, it's possible but it can suck, but then no one thing has to do it forever.
Utters up ! Fan that ember , and just don't deprive it of its needed oxygen. The hummies only keep coming back to the feeder because what's in there is good, stay away from bad 'feeders'
