We were honoured to have you here at the University of Burdwan dear Suborno ❤ You even visited my department ( Department of Chemistry) that evening on 23rd April but I had left for home earlier and couldn't meet you. I attended your seminar in the auditorium that day but didn't know that you'd be coming over to my department too...if I knew I would have stayed back and not left.... I really wish I could meet you in person someday and see you again ❤ Thank you so much for delivering such an interesting lecture that day... I wish you all success and happiness in life ahead 💐 May you reach all heights you ever wanted to ❤ Allah bless you 💖 ___ much love, Nasrin (PhD research scholar in Chemistry, BU)❤
