So you know how Snape gets mad when he sees Harry peeking through at him and Filch

And Harry immediately assumes it was because Snape's up to evil and got busted for it (although it's more than likely it was actually because Harry wasn't supposed to see this at all)

Well, I have a lil theory about the actual reason he got mad

See this:

This is what Snape was saying before he sees Harry.

So I present to you my theory:

Snape was actually just embarrassed because Harry caught him whinging like a twelve year old in his natural Severus voice and not the Professor Snape voice.
