Unclear Conversation

How come you stopped liking the Big Bang Theory TV Series? You were the one that introduced me (again) to the series. You were so excited the first time we watched it.

Maybe it’s because there was a time where I was supposed to watch it but I didn’t feel it.

What do you mean?

I feel like I need to be awake at certain times while I’m supposed to be sleeping.

Tell me, do you know what he meant by this?
