Thank you for your kind wishes and encouragement, I managed to finish the paper and emailed it to the organiser at about 8.30PM on Saturday.
Yup....spent the whole of Saturday in office. :(
The presentation by my Boss went out well yesterday.
P/s: actually my colleagues and I were betting whether my Boss will be presenting the paper or he would just ask me to take his place since I did all the preparation. Well the possibility was there - and it had happened before.
Needless to say, the guys owed dinner now.
