Following up on the above post I wrote, later that day on which I wrote the post, I met my hub and a few of his friends/colleagues for food&drinks. They had been attending a 3-day design seminar. One of the things I talked about was the number 9 (including its mulitples, etc), as I was excited about it after having just read about it here. I admitted that I was being goofy about it, but added, what if there's something to these number synchronicites. They all laughed about this, and yes, decided I was being flaky about it. No problemo, I'm used to this, as I'm excitable and enthusiastic about many things. 
So we all left, went our separate ways; I went home with my son as we were on our bikes and couldn't join them at an awards show/after party. Next day, hub told me that en route to the show they stopped at a red light, someone looked out the window and noticed in an apt. window right in front of them that there were no curtains or blinds, but 3 cardboard numbers, tall and clear, 3,3,3. And it had nothing to do with the address of the building, nor the floor (window was on the first floor/street level), btw. They all looked and joked about the coincidence of this, but that was it.
Hmmm...
Hub also said that he was seeing another number, 5 (his "number") all over the place, since this 3-day seminar had started. He saw it several times, but he'd not kept count of how many times he saw it. I jokingly (not really) said to him, that this number 5 was "calling him", because his last name has a distinct 5 in the pronounciation (if you know how to pronounce it, it's French). He thought that might be true, and felt it was also a positive omen.
Next day, he attended the final day of the seminar, when they were calling out the names of the 3 people who'd win prizes in a draw. He said he stood there anxiously, "knowing" that he was going to win something. Sure enuff, names/prizes 3 and then 2 were announced; and who was the grand prize winner? My husband. He said that the presenter struggled with his last name (which is typical) and he went to the stage smiling, supremely excited for having won a new pc, flat screen monitor...
So a 3-day design seminar; 333 appearing to me and him/others (with whom I'd just told about 9). And repeating 5s appearing to him over the 3 days. Means something?
