user: I need to plan a wedding and I have no idea where to start. Will you help me brainstorm a few things I should do?

assistant: Your wedding a celebration of you and partners love. Here are a couple ideas of where to start. 
1. Sit down with your partner and each share you respective vision, hopes and dreams for your wedding. Listen intently and take notes to what your partner says. 
2. Make a list of the people you would want at your wedding. Tier each potential invite as Tier 1,2 and 3 and who's side they represent (you, your partner, or both).
3. Identify a preliminary budget based on what you can afford to spend. 
4. Make a list of the most important things to you and your partner, in priority order (venue, band, flowers, dress, etc.)
5. Evaluate hiring a wedding planner to assist you in your planning efforts. 
Good luck as you begin this exciting process!

user: How does Spark relate to Apache Hadoop?

assistant: Spark is a fast and general processing engine compatible with Hadoop data. It can run in Hadoop clusters through YARN or Spark's standalone mode, and it can process data in HDFS, HBase, Cassandra, Hive, and any Hadoop InputFormat. It is designed to perform both batch processing (similar to MapReduce) and new workloads like streaming, interactive queries, and machine learning.

user: Please give a simple list of reasons that extraterrestrial intelligence may not exist or is very rare

assistant: Conditions that evolved intelligent life on planet Earth may be exceedingly rare in the Universe. These reasons for that are speculated to be:
1. The solar system is in a safe location within its galaxy.
2. The location of the earth relative to the sun and other planets in the solar system gives it protection from extreme environmental conditions that would prevent life from occurring.
3. The steps that led to advanced life forms (prokaryotic cells to eukaryotic cells, sexual reproduction and the Cambrian explosion) may be very unlikely to occur.
