first of all , I am sorry that I could n't give my feedback earlier . In these two years , my favourite lecture is yours . Your style of lecturing , the commitment you showed have really inspired me . whenever I come to your lecture I come with pleasure . I used to sit in the back because I am very much concentrated and comfortable there , please forgive me sir , if that bothers you . I am sure that you are a big aspiration for most of us . I wish I have all the lecturers lecture like you . I remember that you tapped on my shoulders for answering a question . It feels very much to me sir . I always love this type of encouragement from this university but I only got few . Your idea of a facebook group is excellent . I do n't know how many people follow them but for me , it 's really worthy . So please continue that in the future as well . Thank you for being an inspiration for all of us and sorry sir if we have done anything wrong that hurts you . Thank you so much . You inspired me a lot . I will remember you forever .
