yeah, unless you don't talk, you have an accent of some sort. Accent is just the inflection and sounding of how you pronounce things, so if you talk, you have YOUR way of pronouncing things, even if it's not abnormal to you it's still an accent.
I happen to have a very specific Califonian accent from a specific area of the city I grew up in, because everyone talked that way so I did too, plus a bit of a midwestern 'curl' to my sounds (no, NOT a southern style) that pops out occasionally, especially now that I'm in the midwest.
