I haven't seen Parasite, but it's on my list. Looking at director Bong Joon Ho's filmography, Memories of Murder was an excellent movie, but I found The Host to be a little campy and didn't finish it. Okja looked weird, and along the same lines as The Host, so I wasn't interested. Snowpiercer also didn't peek my curiosity. So I have mixed feelings about him.
But I want to give them a chance now, now that I love Parasite so much.

Because if it's already so much of a risk just to sneak up to the kitchen for food, it's presumably so much more of a risk to sneak out of the house to where more people could spot him (and who knows how far away the nearest mailbox is anyway), plus there's also the risk not being able to sneak back in).
