• Surfing the Internet (reading blogs, looking at pictures, browsing Pinterest)
• Reading (mostly non-fiction / very select fiction)
• Studying Korean
• Watching movies or TV shows
• Spacing out
• Coming up with ideas, brainstorming, creating (writing, drawing, designing)

Alone time for me consists of not talking to or engaging with anyone, and being in quiet surroundings. It's extremely important to me, and if I don't get it frequently I become crabby, tired, and anxious. A few hours (or days sometimes) in solitude and I'm ready to socialize again. Rinse and repeat.
