Pardon me (Almost confused, you don't wanna take was has just been said to you the wrong way but it's making you nervous: You've been caught being deceptive)

I never delved too deep into it, that shit bums me out (The convo has gone to a topic you know a little bit about, it's not a happy subject so you're trying to stay casual: your not lying but you are downplaying how aware you are of whats being referenced)

Yeah I'd heard something going on down there but nothing specific (Something happened this morning and it's being brought up to you: this is an honest response)
