... I'm just gonna leave it here :)
Obi won't let anyone make fun of his padawan, because only he can, but never in a mean way so as not to hurt his feelings.
(I mean, apart from their banter, but that's normal for them and each of them knows the other isn't serious)
I love the idea of Anakin bringing up his experiences as a slave on Tatooine in random moments or conversations.
Imagine that not long after Anakin arrives at the temple, Obi-wan introduces him to Quinlan and Vos tells Anakin how he and Obi-wan used to sneak out of the temple as teenagers and what they did and Obi doesn't want Quinlan to demoralize his padawan and suddenly Anakin comes out with:
"If they ever sneak out I'll be blown up"
And now there's complete silence, both knights are quiet and Obi-wan is completely terrified because his little sweet padawan just said he was about to get blown up as a child with zero fear like it was normal and that's how Obi-wan found out Anakin has a bomb chip in his neck.
Or how during the Clone Wars Anakin was seriously injured but seems completely normal, can stand normally and doesn't complain about pain, and everyone around is panicking and Anakin just says:
"I'm fine and I've had worse untreated injuries"
and everyone looks at Obi-wan because if anyone is to know what Skywalker is talking about then only Kenobi can do it, but Obi-wan looks at Anakin as if he didn't say anything terrible, but inside he is terrified by how badly Anakin was injured as a child and how close he was to death.
Or another story from the war, the 501st and 212th battalions were on the front for a long time and food started to run out, which was complained about in their free time by the soldiers, even Obi-wan, everyone but Anakin and at some point Ahsoka asked her master about it and he only replied that:
"It's not that bad Snips and plus I've been without food for a much longer period of time than a week"
Which made most of the soldiers passing by stop and look at their general with concern, because what the hell did this man survive that he didn't have access to the right amount of food for more than a week, Ahsoka completely terrified looks at Obi-wan looking for some hint or proof that her master is joking as usual, but she finds only seriousness on his face which means that Anakin really isn't joking.
After a while, Obi-wan becomes more and more used to his padawan dropping such information bombs at various odd moments, not understanding how serious it is, but that doesn't mean he is prepared for it, Obi-wan is still terrified every time by what his boy has been through and how normal it is for him.

I have this idea in my head and I need to share it with someone
Obi-wan can't cook, he just can't cook. This man can make a perfect cup of tea, but can he boil water for anything? Forget about it, it will burn it right away. As a Padawan, he had no problem with it because Qui-gon cooked, but then when he took Anakin as a Padawan, a problem began because how was he supposed to keep a child alive when he couldn't even cook the simplest of meals?
Well, the answer came to itself, because after a failed attempt to cook something for breakfast for both of them, Anakin said that he just knew how to cook (his mother taught him to cope if he was sold somewhere) and he's not the worst at it, he's even quite good, and it turned out that Anakin cooked various things for them.
When Anakin got older, he started joking that Obi-wan wasn't allowed in the kitchen because he didn't want him to set the entire temple on fire, which made Obi-wan blush all over and tell Anakin to shut up.
Obi-wan doesn't have the basic skills to function like a normal person, fight with me.
