She's kind of right I think. Personally, it's not that I don't read things if it's late (or sometimes even really early...eheheh), it's that if it's late I can't always think of anything coherent to say about a story. It's probably a silly objection, but I hate leaving feedback that says only "Awesome." or "I liked it." or something like that and often late at night that's all I can manage coherence-wise.

I also do the "open in a tab and read later" thing but then it gets into my weird issues with commenting on old posts. ^^;;

All in all I suspect it adds up to me not leaving nearly as many comments on fic as I should. XD;
