Is it normal that an advisor does not read the final version of the PhD proposal of his student before submission? Recently, I submitted my PhD proposal. In my opinion, something really strange happened to me and that was: my adviser did not read the final version of proposal at all before submission!

I started to write my PhD proposal approximately 3 months ago and the written document went back and forth between me and my advisor for four times but despite I spent a whole day to correct his final suggestions before submission he did not read it at all.

I could certainly say he did not read it because we use a system to upload or store files which could track users, who view the the files or even download it, and this system shows that he did not view or download the last version at all and this last version is not available anywhere so the possibility of accessing it somewhere else is zero!

It looks really strange to me because I'm supposedly his first PhD student ever because he is a new faculty in our department which came to our university just 1 year before I got admission and I think if more experienced professors don't care really about their student's proposals that could be justified probably that they're old or they don't care at all (Don't be picky on me I'm not saying all experienced professors behave this way, I'm just saying some of them!) but I'm his (my advisor!) first PhD student and I thought it would be handled better than this way.

Is it a sign that maybe he is angry with me or something is wrong? Because, the day after I sent him the last version he responded back to me that I will read it tomorrow but he didn't read it even until now that I'm writing this. I'm just feeling really strange because doing a PhD is kinda like the most important event in my life but... I don't know... any idea or suggestion?
Well, if I would pingpong a proposal between me and a PhD student four times, and I feel like my last remarks were mainly fine tuning, then I would not mind accepting whatever the PhD student makes out of it. 

This is a very personal answer, but since we can not read the mind of your supervisor, this still might help.
