For me, it really comes down to energy.

It takes me lots of energy to ignore something. Like someone walking behind my computer monitor. Like someone having a loud unrelated conversation next to me. Like being conscious of my appearance and behavior (out of respect for others). And it takes energy to solve problems and write great code.

I simply can't do it all every day, day in and day out. Monday is fine. I can work long hours on Monday in the office, getting lots of good work done. But on Tuesday, I am irritable and can't focus as well. By Wednesday, I'm useless. If I go into the office, I come home exhausted, unable to even speak.

Fortunately I can work from home, but it's a heartbreaking trade. It's not as much fun (or productive) to collaborate over the internet as it is in person. I am definitely not going to accidentally end up going out to lunch or coffee with a new friend. Etc.

Comments to the tune of "suck it up", "wear headphones", are nothing new to the ears of introverts. We've been dealing with this _extroverted culture_ all our lives. Extroverts thrive on stimulation. Introverts drown in it.
