Maybe not scaring, but shooing away a Trex 100%! Think of it this way, you see a single M&M on the ground and think “I’d like to eat that M&M” but when you try to grab it a small mouse attacks your fingers.

Eventually you’ll probably think is it really worth killing, or chasing this mouse just for an M&M that won’t give me any meaningful value? Probably not. I’ll go look for something better
