Snake or Worm

It rained cats and dogs today so I decided to pull some weeds this evening (they come up so much easier when the ground is wet). It was 8:30pm so there wasn't much light out. I saw what I first thought was a worm trying to crawl up the foundation from the grass (he wasn't having much luck). That's when I thought, shit, maybe it's a snake. By the time I ran inside and got Paul he was gone. I really hope it was a worm. If it was a snake it's either a grass snake or a baby (please not a baby!!!). Either way I am very concerned..... but it very well could have been a worm.
