Yes, you have to be able to trust the other person's senses as well as tyou trust your own. When your partner's spidey sense is pinging you have to pay attention to their demenaor and body language to know they mean it.

I have friends who trust my sense of caution but the only people's senses I trust are those of my immediate family members. I love my friends but of all of them I'm the one most likely to be the cautious one because I'm the one who least cares about being polite to total strangers.
