This little guy looked pretty sad in his cage. His body language was so much like that of a child, and just screamed "I just want a hug!". I put my finger near his cage and he grabbed onto it with his hand and then promptly fell asleep holding my finger. We sat like that for about 20 minutes. Aw. I think the closest thing he gets to love is little kids poking him and teasing him. Monkeys aren't supposed to be in cages.
On a happier note, we saw lots of monkeys in the wild, kamikaze jumping between trees... they looked very happy.
