Oh boy, I'm the same way sometimes actually. But hey, just remember they're probably not even that judgmental toward it or anything, it might just seem like it but they're not.
Otherwise I'm not sure what would be the cause for why we're like that, quite a mystery to me. Maybe it's just being awkward and derpy in general? |D (Not sure how to advice-ify myself, so lol.)
I really hate how late I tend to stay up, sometimes not even on purpose... I just constantly lose my sleeping habits. :L
