saving time

I hate it when people tell me come here and let me tell/ask you something when it's something they could've asked you without you walking over to them. I get this a lot from one PSR and it's usually something like what A1c or something like that. Honestly, unless you want to ask a person a private question in a public avenue, i don't think you need to have them stop whatever they're doing just to hear somethng they could've heard while away. Afterall, we listen with our ears.

My roommate yells "come here for a minute." Not wanting to get out, I tell him i'm indisposed and asks if he needs something. He tells me i'm leaving it at your door, i was paying my bills. Obviously, it's rent check. He's notorious for that and after going through it the first weekend, i've made it a point to respond to him without going out because it's always been him showing me something he either could've told me about or something i don't care to know about.
I mean, at this time, i'm usually sleeping. I don't see how he expects me to get up from bed to come pick up a check that he could leave at the table like the last time.
Maybe, it's my fault. I already have a sign on my door that says "please leave all communications at my door and i'll respond asap." maybe i should get something that says "do not disturb."

The last thing i need is to be interupted while taking a FL exam. Honestly if that happens, i'll not respond.
