I remember when I was about 7ish years old -- we had this neat and lovely park near the neighbourhood where I lived in San Rafael...family and I'd go there and spend a few hours, frolicking around and having a picnic. There'd be quite a number of squirrels there who were bold enough to get closer to me and retrieve any food I had in my hands. One time -- a squirrel was brave to sit on my knee while I crouched closer to the ground to feed them. That one refused to leave until I was completely out of food, 
Today -- I don't see a lot of squirrels where I live -- not well populated of squirrels, but possums...not those ugly fugged ones in USA...:roll: Those possums are quite daring to get as close as possible to humans if they're desperate enough for food. 
A few possums were brave enough to try climbing on my leg and try to reach the bread loaves I had with me! (Not only bread loves, but vegetable and fruit scraps as well)
