Tattle tale

So today after school when I was going to my bus, I told my friend Eli that I was in his e-mail account.(Once when Nathan went to his house, Eli logged into Nathan's ipod touch to check his mail and never logged out.) So I was joking when I said that Nate told me his e-mail and password, (I don't even know his e-mail) so Eli comes over to me and grabs my shoulder super hard and says in an agitated tone, "Log out of my e-mail now!" and of course a teacher saw it. So now I have to tell him that I logged out even though I never was in. Eli is tattletale.
