Context: The day started off badly when I awoke in the bathtub . This was around 5AM , and I was not certain what had made me decide to curl up there , fully clothed , in the hostel 's bathroom for the night ; but I knew I did n't want to stay there , so I quickly pried out my contact lenses ( by this point solidly adhered to my eyeballs ) , washed my face and snuck into the dormitory next door . I figured I would sleep late , perhaps until 10AM , then go normally about my day in downtown Budapest . When I did get up , after 11 o'clock , it was with a vicious Harpy of a hangover .

Question: What may be the reason for their contacts being stuck to their eyeballs ?
Options:
0. They have a dry eye condition .
1. They went swimming with them in .
2. None of the above choices .
3. They are using expired lenses .
Answer: 2
