Frustration

I didn't get to play this out since someone was a little slow on the uptake... So I'll try my best to release the bit of creativity here.

Seth lit another cigarette, blowing the smoke from his mouth before saying, "It's a good thing Mara never had kids. I'm terrible at picking out names." It was said so casually that it took Rhayvin by surprise. He had never heard the name before, from Seth or otherwise, and for Seth to disclose that sort of information, something so private; well, he was starting to feel like the kids dad even more, despite Seth's rude insistance that Rhayvin was nothing of the sort and never would be.
But Rhayvin couldn't help be curious, and since Seth seemed willing to share her name, perhaps he'd share more. "Who's Mara?"
Those two simple words would freeze Seth, fingers stalled over the strings of the guitar, mouthful of smoke caught in his throat. After a few seconds, he'd exhale and lower his gaze to the guitar, not saying a word.
Rhayvin frowned when he saw that. Perhaps it had been an accident, his mentioning Mara.
"I haven't thought about her in a long time," Seth finally whispered. A few seconds more and he took the half-smoked cigarette from his lips and crumpled it in the ashtray beside him.
Feeling that Seth would need to be pushed to disclose more, Rhayvin gently repeated his question. "Who is she?"
Seth looked away, visible pain wrenching his face, biting hard on his lip to keep back the tears. Sure, he acted tough, and may have lived a long time, but he was still a kid. "She was..." he managed, before his throat tightened and choked off his words. His hand lifted to pinch the bridge of his nose, in attempt to calm himself.
Rhayvin sat quietly, letting the boy work it out. And it payed off.
"She was my wife."
