I have many to choose from but here's mine. When the 11:11s started for me a little over a year ago, I started to try testing it but quickly realized it would never happen when I expected it to. It would always take me by surprise in some way. One evening I hadn't looked at a clock in a while. I wasn't really sure what time it was but I suddenly got the idea in my head that it might be 11:11 time. I rushed to the kitchen and looked at the clock on the stove. It read 11:13 and I thought, "Bummer, missed it by 2 minutes." I then turned around to cook something in the microwave and BAM, 11:11 right there in front of me! I guess the microwave clock was off-set from the stove clock by a couple minutes. I laughed because it still managed to take me by surprise somehow.
Although I did laugh, this was actually at a time when I was still slightly creeped out by this whole thing. So it was sort of like in a horror movie when a person hears a noise in the closet or something, walks up to it all tentatively and quickly opens the door to only find a cat or something. Then after breathing a sigh of relief, they turn around only to find themselves face to face with a knife-wielding maniac! Well, it wasn't THAT scary, but you get the point. :D
