yeah.. I don't even do well when my wife walks around behind me while I am working, and she's my wife! Usually just wait until returns to her office desk. It's just something innate in me, I don't know what it is. I know some people (very small minority) have the ability to get into flow no matter the situation, but I don't.
I have the same thing and I think it’s because there’s a chance she might interact with you, which is enough to prevent you from getting 100% focused. Just having someone close enough that there’s a chance they will distract me is enough for me to feel mildly distracted by that possibility.
I'm the same. The mere presence of someone that I might interact with throws me off. I worry that I'll have to interact so block myself from focusing on the off-chance I'll be thrown out of focus.
