Ok Ray, maybe we should ask you to explain.... Tel us with the T on your face, what behavior will it have to warn you it's going to bite you? To my mind in the photo it's sitting on your eye, right ? If it's just walking on something it doesn't see as something other than say, a stick. Couldn't it come to the realization that your eye is soft and moist and suddenly decide to try and eat it? What would your reaction be? Will your first instinct not be to hit it away from your face? Would you then first look if the T is alright, or would you run screaming to find help or something to try and fix the excruciating pain you will be feeling where the bite wound is ?
If a tiger wants to attack, will it growl, or will you see it crouch down etc? what makes you think a tarantula is ok to handle?If you gently nudge it toward your hand and it get's up, is it ok to handle it? What does it do to make you decide that it might not be ready to be handled on the day ?
Please note, I am not being sarcastic or condescending, I would really like to know what the warning sign is to look out for.
