didn't I already do this?

Tonight as I was preparing to go to bed, I went to brush my teeth, it felt as if I just did it, when I sqeezed the tube of tooth paste, it felt so familiar that I must've done it not long before, that sensation was too close to be this morning. So based on my feelings I reached the conclusion, I already did this. But then I examined my teeth, no, it doesnt feel like its been brushed yet, and if it has been brushed, clearly i didnt do a good enough job the first time...feel like i'm going momento.
But the facts spoke louder, so I obliged to bend over the sink and brush..."once again", then it sorta struck me, recently, there are coutless times where God has lead me down the same path, the similar trials, similar problems, similar people, that lead me to ask him, didn't I already do this? And a lot of times I lose patience and just wanna get it over with, but to be real with myself, did i do a good job in the first place? Did I love with my mind, strength and soul? Did I love him/her as myself. Could I have walked the extra mile, or turned the other cheek? If the answer is yes, then I better get my ass in check and do a decent job this time, its too late to change the past, but its still too early to say i've already done this.
