It really embarrasses me when I meet someone new and that person is really shy and introvert! A month ago a friend of mine introduced his sister to me and she was so quite that she barely spoke.
The problem is, I was very shy as well and I didn’t feel comfortable telling too much about myself. I’d prefer to meet someone who I have less in common with, that is to meet someone who’s very talkative and extrovert so that I would feel more confident in introducing myself and sharing my thoughts.

He would argue that there are many of his own contemporaries that think and develop their ideas just like Aquinas did. You can use this as a starting point and develop your essay.
