If I ever shake someone's hand, I'll apply grip strength according to their preference. So for instance, if someone shakes my hand and applies a grip strength like they're trying to choke someone out, I will squeeze their hand like I'm trying to make sure they lose blood flowing to their hand. Although if someone shakes my hand as if they're shaking it like a lady who's waiting for her hand to get kissed, I will shake their hand with such a light pressure that they can barely even feel my hand there. Also though, if someone shakes my hand and does more than three or four shakes, I will physically let go and pull my hand away from that handshake just to tell them I'm done with whatever's going on. Also though, sometimes people will take 30 seconds to say something they could have said in five. So yeah, I'm just basically letting them know like I'm done with this. Goodbye. Bye!
