I'm not sure this would qualify as love as first site but it was more along the lines of like at first site.

The night I met my husband (thru work) I had the proverbial love at first site 'lightning strike'. It wasn't instantly upon meeting but was after we had talked for about 3 minutes. He smiled at me and out of nowhere I felt an electrical sensation hit me from my head to my toes. I remember standing there thinking "what the heck was that?" And from that point forward I liked him immensely.
