OOC Preferences

Backtagging: I'm bad at remembering to backtag after a few days, so if there's a thread you want to continue please ask me! I won't be offended.
Threadhopping: Go for it.
Fourthwalling: What is the fourth wall even in Homestuck. If you're doing it for the luls, go for it.
Canon puncture: I'd rather not, but ask me if you really want to and maybe we can work something out. Which characters would even know his canon though seriously.
Offensive Subjects: As long as it's in-character and not done for ~*edgy shock value*~, nothing really bothers me.

IC Preferences

Hugging: Dave is not the most in touch with his emotions. Hugging would be awkward.
Kissing: See above, except he would outright avoid kissing.
Flirting: On the other hand, he will gladly reciprocate flirting attempts (regardless of gender) and escalate them into outright sexual harassment for ironic purposes. You have been warned.
Fighting/Injury: Yes please.
Murder: Yes always.
Mind-reading: Go for it, but give me a heads up so I can tailor my comments to what's most useful for you.
Mind-control: I'm okay with this, but let me know first.
