Bottom line for me is that Klopp himself keeps re-asserting that we've all got a job to do.
Absolutely anything can happen in the last 15 or so minutes of a match, so unless we're 4 up and in cruise control, assuming the win's in the bag is mighty complacent, and certainly not befitting followers of a club like ours, who should by now be very accustomed to the possibility of late dramatic twists. Likewise, if you leave just assuming we've already been beaten or can't possibly nab the required points, then that's a bit rubbish in another way for a football supporter; you're there really to provide encouragement and inspiration right to the death, and lift them when their heads have dropped both during and immediately after the match - you aren't simply a paying spectator, that's for another sport.
Getting home a bit earlier just is not worth it considering how pathetic it looks, people streaming out of the ground with plenty left to play. You could avoid the rush by staying in Town for a bit, making more of a day out of it. Fair enough, if you're a regular matchgoer and a local there eventually won't be much new for you to see or do, but it's a small sacrifice that you should be willing to make if you want the honour and privilege of closely following the team as it challenges again.
Is us losing a complete waste of your time and money? It's just not a good way to think about it, purely in terms of personal convenience. You might well regret having missed those little moments later in life, and probably won't reminisce fondly about all those times you got home a bit quicker just to turn the tele on and watch some shite or other.
