I kind of do the opposite, I am big as fuck. But that just means they are more likely to see me as scary instead of gentle. Intruders that get scared are much worse than intruders you can talk to. They might get desperate and do something much worse than steal a bit of your stuff.

So before they see me, I let them know that I am very big but not a threat. So it is less of a surprise and more likely to lead to a conversation rather than a confrontation. You can keep my stuff, I just want to keep my life. I can get my stuff back, or new stuff, I only have the one life, and it is irreplaceable to me.
