Shining happy people?

I just had to briefly share this experience as a followup of yesterday's post:

My parents sent me flowers last week - ordered them via internet I guess? The delivery lady showed up at my door and handed me a big bouquet, but I needed something to put them in - I had no vase since a vase wasn't on my list of necessities to buy as soon as I moved here, but I found a quart-size measuring cup in the cabinet that was big enough.

Roommate Phillip knocked on my door today asking if I knew what happened to a missing measuring cup. The conversation went something like this:

P: Have you seen a measuring cup that was in the kitchen?
R: Oh, yeah, sorry - (briefly explained story and why I taken it). I'm really sorry! They're pretty much dead now, so here, I'll empty and wash the vase and put it back in the cabinet now. (proceeds to empty and wash)
P: Well, I needed it last weekend and I couldn't find it.
R: I'm sorry! I didn't know you were looking for it!
(meanwhile, P followed me into the kitchen and is watching me wash the "vase")
R: Oh, well, do you need it now?
P: No, but I might this weekend. You know, if you're going to keep flowers, you should buy a vase.
R: Well yes, I know that, but I didn't know I was receiving these flowers, so I didn't have a vase ahead of time. I didn't bring one with me from the U.S. Sorry I took your cup when you needed it.
P: Well why did you use this measuring cup?
R: I didn't have a vase and I had nothing else to put these flowers in. This cup was the biggest thing I could find. Sorry!
P: Well, I asked everyone else if they knew where it was but you were gone this weekend so I didn't ask you (my reaction: but it's Friday! that was six days ago!).
R: Yes, I was out of town. Sorry I had your [stupid] measuring cup!

Geez! What else do you want me to say? If no one is ever around, how am I supposed to know and ask what I can use?
