After I took part in a meeting which is supposed to make couples, I sent a female attendee to go somewhere in spring vacation, only to be suggested that we should go somewhere with 4 members.
Then, I held counsel with my senior researcher to understand why I was rejected to date only with her. He said "Of course. You must be scared by her if you try taking her alone."
Few days later, I sent an e-mail to my another senior researcher who is in good terms with her sweetheart. It was because I wanted to ask her about the problem. She also agreed with my senior researcher's opinion. So, I must be definitely scared by the female attendee.
Oh, I felt how difficult it is to attract females.
