I get called hon and sweety all the time, What do people mean when they call me that?

Like all language, region and intent are what matters. People in the south and in rural areas use "Hon" quite a bit. Sweety is kind of the same thing. Ive seen a lot of moms use versions "sweety" a lot, likely because they use it so much around their kids.
Some men that use "sweety" could absolutely be hitting on you or just being creepy.
