Want a tattoo... can't decide on a location?

I really want to get the latin phrase "veritas lux mea" (truth is my light) tattooed somewhere on my body. I don't want it big, either. I'm thinking fairly small script. The catch is, I want it to be somewhere hidden for work purposes. Also, I don't want to get it tattooed anywhere that might stretch when I have kids. I know that kind of limits locations, but any help would be appreciated.
