A.N because he's Batman.
DISCLAIMER: I own nothing. Stay away from me!
begonias
Bruce Wayne likes having a garden. He also likes tending it himself because there is something amazingly normal about planting a garden. Even if he keeps killing the begonias. But of course, when Flash finds out ( from Nightwing, who else?) he denies it furiously, and no one argues. Because he is the god damn BATMAN.
" aw c'mon Bats, just b'cause you can't keep begonias alive doesn't mean you have-"
" because i'm batman."
Flash has no idea what his point is, but somehow, he knows it's been made. No one ever mentions the begonias again.
cookies
Bruce Wayne adores Alfred's cookies. Just like everyone else. But when he eats some in the watchtower lunchroom, pretty much everyone stops what they're doing and stares. He ignores them ( because he's batman for Christ's sake...) and continues eating HIS cookies. When Flash appears next to him, he mentally groans, because he's sure that he'll have at least five cookies missing before Wally is gone again.
" hey bats?"
" no."
"why not?"
"because i'm batman."
Flash doesn't ask about his cookies ever again.
fashion
Wally is talking to Dick over a plate of Alfred's heavenly cookies.
About Batman.
Batman's choice of fashion to be exact.
"-and why does he have to be so dark and gloomy? It's scary. I thought the supervillians are supposed to be the scary ones." Dick rolls his eyes and lets out an exasperated sound.
" because Wally. He's batman. What else is he supposed to wear?"
breakdancing
Bruce groans as a eight year old Wally West runs from where he was happily blabbering to Dick (about some nonsense that would only ever make sense to the two of them), because though rather adorable, he is awfully annoying.
" Bruce?"
" yes Wally?"
"can you breakdance?"
for once, Bruce cannot answer with the words ' because i'm batman.'
