Recently a colleague at work was given a bridal shower.  That morning, I went to buy a card to wish her well.  I found a pretty card with a wedding dress image on the front.  I picket it up and wanted to buy it.  But as soon as I held it, I knew I should not buy it.  I did not know why.  Later as we sat watching her open her gifts, she opened a card from someone else, and it was the card I had put back. 

Clearly, my warning was that someone had already chosen that card for her.  But why would my future sense give a warning on such a trivial issue.  I don’t really care if I give her a card she already has.  So why would my subconscious, some other entity, or worse the universe at large care about that enough to warn me?
