Interactive wizards portal for determining dependency:

https://www.irs.gov/help/ita

That portal has lots of wizards, such as What is My Filing Status? Who can be claimed as a dependent? Do I qualify for XXXXX?

No.

I like those kind of answers.  Sometimes answers here get to be so long that I get distracted in the middle or fall asleep.  I started to doze off just a little as I was reading your post, but I snapped right back and was able to finish reading it.

When I have these long answers I try and throw in something shocking or mind provoking to keep the readers interest.

"No."

TL;DR
