When thy last day?

Not sure if I got the title correct. Anyway, I have to give my Mechanical Lead my decision on whether to withdraw my resignation or to proceed on. He gave me throughout the weekend to make a decision. I didn't think much about it throughout the weekend as you can see that I am really busy with the photography outings and such.

Early in the morning, my ME Lead ask me to a room and talk with me. He wanted to know if I have given a thought as to whether I want to stay or leave, but my answer to him is that my decision will stay (my decision as in to resign). He respect my decision and say to send in a soft copy of my resignation to him so that he can forward to HR and advice on my last day and I did. I just email to him my resignation by the end of the day and looking forward to see when will be my last day.

At around 10:15pm, as I was on my way home, my Engineering Manager who is in US, message me and told me to attend a conference call. I was very stunned as this notice came so sudden. But still, I rush back home to attend the call, thinking that it will be related to the things I'm working on. Much to my surprise, my Engineering Manager said that the conference call is just between me and him. He very much like to know my reason for leaving and will like me to withdraw my resignation as we have worked together before and he appreciate what I did.

I was still recovering from my shock (yes, didn't expect him to talk about my resignation) so I just said I'm tired and thought of studying and so maybe it is time for me to move on. He requested that we talk face to face when he return from US next Monday and will like me to hold on to my resignation for now.

I guess it will be better for me to talk with him in person and I also like to offer my apologies to him for leaving at such a timing. Anyway, I guess all I can do now is to hold on to my resignation and look forward to my EM's return so that I can confirm when will be my last day.
