Yay! I spent all of the previous weekend surrounded by people. So after dinner on Friday, when I said I didn't want to go to the party, everyone looked at me funny. Frankly, I couldn't take a few hours of loud music, shouted conversations over said music, and general high-energy insanity, even if with people I like. The reason I gave was, "I'm tired," but what I really should have said was, "I need some alone time."

And, yes, online communications suits me better for much the same reasons as you list.
