My work phone is specifically partitioned to separate personal and work activities. I can't even copy and paste text between the two sides, they are so disconnected from each other. This is done specifically so people can use their work phone for personal business without cross-contamination.
I still refuse to use my work phone for anything but work. I only log into my personal accounts long enough to install/update a few apps from the Play Store that aren't allowed on the work side but are still useful (MS Teams, WhatsApp).
Part of that is not wanting to enter a 12 character password every time I want to do anything simple . But the other part is that I just don't want to mix my personal and work lives more than I have to.
I proposed to my wife in the middle of our dingy basement apartment with no one else around. We were going out to dinner with our friends that evening to celebrate her PhD thesis defence. I asked her if she was okay with a public proposal. She said no.
So, I grabbed the ring (which she had helped me in part to pick out) from where I had stashed it and handed it to her with no ceremony or fanfare.
It was honestly more fun waiting for our friends to notice that evening.
