I've noticed there's more than that going on. There must be some sort of advertising program, or cookies in my computer, because if I go to another site, like amazon, and look at dog feeders, for instance, the next time I come here, up pops dog feeders. Also, I have gone to truck sites lately, and when I come back here, up pops advertisements for those trucks.
Don't believe no one is watching you.
