By December 11th

After:  I had a productive meeting with a client yesterday. After delivering our presentation and demonstration, they were very interested in our services. We exchanged ideas and opinions on how their next generation system should be like. At the end of the meeting, I told them that we don't have much time to complete the implementation by the end of March 2027. The client asked me "Do we need to make a decision by December 12th?" Then I answered "Dec 11th would be fine. There is no strong reason, but it is my birthday." We all laughed.
