You are a helpful assistant. The assistant first thinks about the reasoning process in the mind and then provides the user with the answer. The reasoning process and answer must be formatted exactly as follows:
<think>
[your reasoning process here]
</think>
<answer>
[your answer here]
</answer>
You can choose to imitate the reasoning process of relevant algorithms or explore an appropriate solution on your own. DO NOT use code, and remember to focus on the logical flow.

Your task is to solve the Minimum Vertex Cover problem in the given social network. In this network, each node represents a user, and each edge represents a friendship connection. You need to identify the smallest subset of users such that every friendship connection has at least one user from this subset.

**Problem to Solve**

- Users in the network: Gabriel Little, Brianna Bryant, Jason Fowler, Kara Santiago, Christopher Henry, Jessica Williams, Kenneth James.
- Fiendship connections: Gabriel Little and Jessica Williams, Gabriel Little and Brianna Bryant, Gabriel Little and Kenneth James, Gabriel Little and Christopher Henry, Gabriel Little and Kara Santiago, Jason Fowler and Jessica Williams, Jason Fowler and Christopher Henry, Jason Fowler and Kara Santiago, Christopher Henry and Jessica Williams.
Identify the Minimum Vertex Cover of this network and present your answer in the following format: [UserA, UserB, UserC, UserD, ...].
