Most works from antiquity were written by "well off dudes" since they didn't have to do back breaking labour to avoid starvation. It turns out that most noblemen don't enjoy writing about grubby peasants.

More specifically Letters (epistulae) by Sidonius, Pliny and Cicero might be what you're looking for. They're more mundane and typical than some of the other stuff.

This, historians actually get annoyed a lot because most of the depictions of past life are solely about those who were affluent enough to bother to record it. The daily lives of peasants in most periods and areas are left to be referred to with basically just the facts that apply to all peasants with the occasional odd detail that slightly fleshes out the individuals, like how medieval peasants were essentially weekly party animals because every saint's day was a small festival.
