It'll come back. Like riding a bike. Or singing.
Old skills are like neglected puppies. They're wary at first, but really they can't wait to jump into your arms and lick your face again.
Lately I find I can't write anything at a computer. Don't know if it's the glowing screen or the distractions or the association with work, but my brain just shuts down. But with a pen and a legal pad I can go for hours.
<3 I'm happy you're still writing. I suppose there's phases and phases. I've found, too, sometimes when I put too much pressure on myself to write, the screen becomes off-putting. Little notebooks become like running away. I hope you're good, my dear friend.
