the cards stop coming.
and
your opponents cards or stupidity stops when your cards come.
and
flops don't flop on your side of the fence.
and
you lose coinflips.
and
you lose obvious advantages.
and
you think, since you are losing money, that you are playing badly; then you adjust a perfectly sound strategy and lose MORE money.
and
you question your poker abilities because these days have happened sequentially.
and
you get frustrated in life because you lost money (sounds like gambling addiction....

).
Well at least I know that probability says things will have to change at some point in the future.
