Everyone is in a different time zone.
Between Ohio (your state), and Hawaii it is 6 hours difference.
Prime time, is different for everyone.
But in the odd hours, like dinner time or after midnight, not many may be here. Since that is when many are with the kids/making dinner/doing the homework or bedtime routines etc. And if some are here after midnight, it is because that is the time they can get to themselves. But other than that, they are sleeping.
Or on weekends, many are not here because everyone is home or not home, and weekend schedules are busy.
So yes, responses vary per what time you post a question.
For me, I am online here and with other things, when the rest of my family is not home. I work part-time too. Nights and after the kids & Husband are home, I am not here so much. Nor on the weekends.
