Appreciated the excellent teaching on conversational Analysis. I forwarded the part 1st & 2nd of the lectures to my son named Faisal Khan studying there at Westminster University ,UK. He told me that you are his Prof at this University. Good to know and are happy that my son improved a lot. I hope that my son will gain his education at one of the prestigious Universities of UK. Many prayers for you sir. Iqbal Hussain Associate Prof of Math.
