Leeds Alumni Meeting in Tokyo

I had worked for more than 12hours and I thought I should skip today's Leeds Alumni Meeting in Tokyo to save my energy for tomorrow. I need to wake up about 5 hours later now but I want to say it was good to meet people who are related to Leeds in some way. I know some people I have met in Leeds and I could talk to some business people sharing each experiences in Leeds. I felt time flied. I was planning to be there for 30 minutes but I was there for 1 hour and half.
