I try not to sweat the petty stuff life is way too short. I get declines all the time and only a few of them ever hit my no trade list and that is usually after multiple declines or to many offers of junk wax era commons for fairly big name cards usually inserts. A good example is someone who keeps offering 90's Donruss commons for Aaron Judge inserts the first few times I countered with what I felt was a more balanced trade and they declined with no message or counter offer. So when they made basically the same proposal recently I politely explained that I was not interested in the same song and dance again so I was declining his offer.
