Regarding the OP, I think Lambo has a point, but...
Firstly, Folk are calmer this season than in some previous, possibly because it's easier to remain calm when the table still looks good after a poor match.
Secondly, you can't generalise. I can only speak for myself, but when we play badly I generally put it down to a bad day at the office, no more, no less. I don't believe that I know tactics better than Ronald, and I don't ever feel that a player isn't trying. I do feel the joy of a great performance though. I can still feel the buzz from a midweek game against Arsenal a few seasons back, which we drew, but what a game!
We all know people (and please let's not name them!) who swing wildly from ecstasy to devastation on a weekly basis. Others never do.
Speaking of "if", I did like the MOTD comment about how Sturridge is great if he's fit. "That's a bigger if than Kiplings"

Kipling's poem talks about "treating those two imposters just the same" and I think the point he is making is that in youth we tend to overact to life's minor events, not that we should treat a loved-ones tragic early death and the birth of your child in the same way. A football match is ultimately as unimportant an event as it is possible to imagine-a group of men kick a pig's bladder around a field. You might walk away feeling grumpy, but switch on the news and that soon lends some perspective.
