He grinned, a broad, genuine expression. His shoulders felt loose, his body relaxed. He felt an urge to dance, to spin around in circles to release his feelings. He quickly switched to his favorite music.

He grabbed his phone, excitement driving him. He'd spend all day reaching out, making connections. The world seemed brighter, full of color. The usual anxieties and daily worries seemed to melt away.
