Is it weird that I just think this would be kind of adorable?

John is probably so used to seeing occasional glimpses of Sherlock out of the corner of his eye, only to find that he’s not actually there once John turns around, that he doesn’t even react anymore.  He just takes it for granted, and anyone he actually opens up to about it gives him a pitying pat on the shoulder and tells him things will get better in time.  When he finally sees Sherlock for real, he just thinks “Full-on hallucinations were probably only a matter of time, right?”

This is actually what I want to happen now.
