Nothing I do is normal. 
Okay, Iām exaggerating. 
There probably isnāt anything that the neighbours can see, especially with all our windows UV-tinted and blackout curtains all over. Plus, our balcony isnāt yet set up for activities. But if they could seeā¦ Where do I begin? 
I suppose in terms of witchy things, letās start with the stuff I own. I have witch bells on my door, little bundles of crystals and things in various places, and a growing witchy corner in the room with all the computers. My partner calls it my shrine.
In terms of things I doā¦ Iām not sure now that I think about it.
Often, itās very hard for me to think of things when Iām trying to, and very easy when Iām not. Iāve had so many moments where Iāve thought to write down what Iād just done so I can answer this question since you made this thread and then forgotten to write anything down 5 seconds later. 
In a mundane sense, I obviously behave with my partner much, much more weirdly than I would ever reveal in front of the world. I was dancing with one of my cats last night while I was waiting for my partner to finish cooking. Iāll pretend to creep around like a cartoon villain/goblin. Iāll make up a weird ādanceā on the spot. Iāll follow my partner around the unit so closely that Iām constantly in the way of them doing anything. Iāll talk about our cats as though theyāre humans doing crazy things. (āCome look at the boy! Heās licking his butt and looks like a Thanksgiving turkey leg!ā) Iāve been told Iām very animated, like an anime character from a slice-of-life show, by quite a few people now. 
Oh, that reminds me. There used to be a little magazine/newspaper thing that was handed out at train stations for years for free by volunteers. It always had a section called āOverheardā where people could submit something they overheard another say on public transport that was funny. One time, I found myself in there. Iād gotten onto a train with a friend and said, āLook! Humans! Humans everywhere!ā Or something like that.
And thatās definitely not the weirdest thing Iāve said in public. I say a lot of things in jest that I donāt mean because Iām usually talking to someone whoās known me for years, and we just know. But to random people, it will sound crazy because Iāll say it like Iām dead serious.
In terms of witchy things, I suppose you could argue anything I do would scare my neighbours or make them question my sanity. 
Anything involving candles probably looks like a scene from a horror movie where something evil is being summoned by people who donāt know any better and Iām two seconds off unleashing something that will consume the whole suburb.
Considering I want to start doing some of those on my balcony, too, because of moon- and night-related goddesses, itās going to look weird.
Plus, Iāll speak some Latin with certain spells. Itās not great Latin, since I only studied it for a few months in school. But I sound confident enough that someone who has no idea might think itās good. And I like it because it kind of obfuscates what Iām saying, almost as though itās a secret language.
Funnily enough, bodily movements are probably the least weird part of my practice. Someone could easily assume itās just some kind of meditation method or even just bad Tai Chi or something, given how Asian the suburb is.
Okay, this is already a wall of text. Sorry. 
Iāll be back if I think of or do anything super weird, though. 
I love that you have a sunroom, too - thatās one of my wishes for my ādream houseā lol and hopefully your neighbors keep to themselves!
Itās good to know Iām not alone in my perceived ācrazinessā from my neighbors 
Then I might meow and talk about rituals Iāve done and goddesses Iāve met
