Did You Say Something?
There are all sorts of wild and crazy things you can do to avoid social situations. However, what happens when you actually need to take a bus or train to work? Thankfully, at least in our modernized societies, striking up a conversation with the person sitting next to you is a huge social no-no.
Alternatively, you can do what Wendy here does: take a book with the fake title Stabbing Strangers who Talk to You, and make sure people can see the cover clearly. The best thing is that they won’t just not talk to you, but they’ll also respect your 3 feet of personal space!
