Oh, that Piccolo! He's definitely stoic and laconic. I'm sure he's rife with wisdom ... but I've always had trouble getting it out of him. I actually tried for a long time to find the best way to converse with him, but he just didn't seem to respond well to any of it. It's almost as if he found my dialogue to be tiresome and annoying. Huh! Well, I'm sure he appreciated the effort. I would love to have a discussion with him one day when he's up for the socialization. I don't even care what about. He just seems to know his stuff! ...Whatever it is.
As for Ms. Chichi-san - what a great conversationalist and gracious host! Her presence is definitely a strong and self-determined one, and while she seems to have an air of honor running through her, she will not hesitate to complain about anything that's bothering her. Even if it's about someone else and it may be uncouth to divulge. Makes me wonder if anyone talks about me like that behind my back. Well, if so - I doubt they could spin it into the same fiery and captivating conversations that Ms. Chichi can perpetrate.
However! She can be very ... specific! She wants things done a certain way, and you best not intervene. She especially won't have you in her kitchen asking questions about her craft while she cooks. Even if you were just trying to warn her that you lack the same appetite as the other Saiyans in her life and you're trying to save her some time and effort. And maybe your stomach from exploding. She is an EXCELLENT chef, though!
You know, it's funny you mention both Piccolo-San and Ms. Chichi-San here in the same ask like this. I'm not sure I've ever seen them in the same vicinity since I first came to Earth.
But don't let that fool you! Maybe it's not mine to share, but I feel I must - I've heard through the grapevine that Ms. Chichi-San and Piccolo-San used to be close. Apparently, a few years back, when Son Kakarot was, well, dead, his friend Piccolo stepped in to help the grieving family through their loss. He and Son Gohan evidently go way back, and so I suppose that graciousness was extended to the Son mother and her new babe. During that time, Piccolo-San was there to offer comfort, help raise the kids, and I believe help with whatever domestic chores are involved in homesteading. I can imagine him chopping and hauling firewood, for instance - he certainly has the arms for it! One is to assume that he and Ms. Chichi became close confidants in that time.
...But something about the books in Mr. Piccolo-San's possession makes me feel like there's more to that story...
