Answer the question about text:

My workplace did our summer staff fun - event today , which involved going to the National Zoo . We went to the Panda House first . There , Tian - Tian took a big fucking crap right in front of me . He 'd been eating some bamboo , and then got up to take a long drink of water .

What may be the reason why the animal went to the bathroom in the open ?
Animals do n't need privacy to go to the bathroom .
