Aged wine or expired spam

My sister and I were talking recently about my single-ness. She set me up on a blind date with a guy she really knows nothing about which is awesome for me because it's kind of like a grab-bag: you reach inside hoping you pull out the giant candy bar and instead you pull out the mini yo-yo that doesn't even work. It's tricky being "older" (I am the ripe old age of 29...) and dating because you start eyeing each other with mistrust from the very beginning. No matter what the other person seems like on the outside, there's that question lurking in the background-Why are you still single? If you're really all that, shouldn't someone be dating you? This applies of course to everyone except me. I'm still single because...well just because. So my sister and I were talking about this blind date and I asked, so why do you think he's still single? And she responded with, "You know Mallorie, there are those guys who are single because there's something strange about them, and there are those who are single just because. What you really have to find out is, are they the old out-of-date spam, or are they expensive aging wine?" And so I ask, who am I really? Spam or aging wine?
