Everyone seemed to have their own family except him. Gohan and Videl were awaiting their second child; even Krillin and Eighteen had a daughter! Goku and Vegeta each had two grown children. Goku was a grandfather and the way Goten and Bra were acting, Vegeta was going the same way.
Everywhere he looked someone had a family. Even when he saw people he'd never met in the street they all seemed to be courting couples or parents with their children. Two mothers chatted away carelessly about their lives while their children played or bickered about petty things.
It was so strange. He seemed to be the only one not.... "moving on" as it were. It had been the same old story for over thirty years. Single. No children. No relationships what so ever. He'd always been alone. Never knew any parent and an only child. Never married or reproduced.
Normally, it wouldn't bother him. But seeing everyone else with things he didn't and never did have made him wonder if he was... "normal." Everyone seemed to have loved at some point. Goku... Gohan... Yamcha... even Vegeta. Of course, Vegeta would never admit it, but he didn't have to. Everyone knew he loved that woman.

So why, Piccolo wondered, had he never loved? He considered love and weakness, and was glad he didn't suffer from it, but nevertheless there was something unsettling about the fact that he hadn't felt it anyway. It made him ask questions about himself. Was there something wrong with him? Or were nameks just incapable of the emotion? After all, what did love bring? Sex. And what did sex bring? Children. But nameks were asexual. They laid eggs. They didn't need to have sex. Couldn't. So what would love bring? Nothing. The feeling was completely useless for a namek. So what was the point in being capable of know it if it wasn't needed?
But then again, what about Gohan? The kid meant something to Piccolo (although he'd never admit it.) It wasn't "love", more like a father - son thing really. Did that mean nameks could also fall in love?
But on the other hand, fathers who loved their children had a tenancy to want to protect them. Maybe nameks could feel a love for their offspring or such for the sole purpose of protecting them. Thus, increasing the chances of the namek race living on. After all, if there were nameks to they eggs they would continue to increase in number.

Namek emotions seemed to be very well thought out. If nameks could not benefit from an emotion, it was eliminated.
Surely that was it. Goku, Vegeta, and in a way, Krillin, had proved that you don't have to be of the same race to love someone. And there were plenty of pretty girls on this planet, some of which seemed friendly and sociable. So in conclusion, it wasn't that Piccolo himself was too cold to love, it was just that love was an emotion any namek was incapable of feeling.
But... then, if there was no point in nameks loving, surely there was no point in this empty feeling he'd had for some time now. It had started around the time Videl had fallen pregnant again, about a month ago. Gohan was telling everyone the good news and getting all excited telling Pan she'd have a little brother or sister, and like a slap across the face it hit Piccolo: he didn't have a family.
And since then, he'd felt kind of empty. He'd figured it must be because he didn't have a family, because he wasn't really lacking in anything else. Nothing that he'd really care about, anyway.
But how to get rid of this feeling? It was starting to bug him, he couldn't concentrate the way he used to. As cold as it sounded, this feeling was more annoying than anything. It only got to him really because it distracted him from his training and meditating. He didn't care that he didn't have a family. Well, he wouldn't like to care, at least. But clearly he did, otherwise this feeling wouldn't be here.
"... Hm." Piccolo shook his head. "Whatever." well, he'd just have to try harder to ignore it. It couldn't stay around forever. He crossed his legs and closed his eyes. He tried to focus as he meditated, but soon lost concentration.
