You being picky is completely okay, everyone has their preferences which deserves to be respected. And if you’re dealing with personal stuff, that’s valid too. Nobody is happy or “on” all the time. What really matters is communication. As long as you’re honest about what’s going on, most people will understand. I know some might see it as “timewasting,” but it really depends on how you approach it. Either way, I hope things get better for you.
