Read the following context and choose the best option to answer the question.
Context: So Nicole held a party to celebrate her birthday yesterday . It was really nice , though she got rather drunk rather quickly and was goofy and skipping around the house and tackling Kent . xD It was nice seeing Adrian and Tony again ( I had n't seen them since the cottage ) , and recalling the insanity of the cottage weekend ! Trevor and I walked home sometime after 1 am , and it was still warm and muggy and NICE .
Question: Why did Nicole get so drunk that she was skipping around the house and tackling Kent ?
Options: 
- None of the above choices .
 - As it was her birthday , she decided to let loose a little and drink to excess
 - She did not realize the proof of the liquor that Adrian and Tony brought so she got drunk fast
 - She is upset with Kent for cheating on her so she is getting drunk and attacking him
