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: Michael Ward, Craig Avery, Andrea Carr, Mr. Alan Salazar, Charles Reynolds, Donald Henry, Jessica Osborne, Christopher Hayes, Terry Luna, Laurie Baldwin, Judy Peters, Scott Saunders, Tracy Moore, Jamie Baldwin, Jessica Luna.
- Fiendship connections: Michael Ward and Terry Luna, Craig Avery and Terry Luna, Andrea Carr and Jessica Luna, Andrea Carr and Jessica Osborne, Andrea Carr and Terry Luna, Mr. Alan Salazar and Terry Luna, Charles Reynolds and Terry Luna, Donald Henry and Terry Luna, Jessica Osborne and Tracy Moore, Jessica Osborne and Terry Luna, Christopher Hayes and Tracy Moore, Christopher Hayes and Terry Luna, Terry Luna and Scott Saunders, Terry Luna and Judy Peters, Terry Luna and Tracy Moore, Terry Luna and Jessica Luna, Terry Luna and Jamie Baldwin, Terry Luna and Laurie Baldwin.
