I can share mine:
My fiance lived about three hours away from me because we had both graduated college and he found a job in the city our school was in...I returned home for the summer because I had work there.
I was visiting him this particular weekend, and though he had already had me show him the kind of ring I wanted (I was/am in looooove with a particular artist's work), I didn't really know when he was going to propose, or how. I thought maybe he had talked to my father already, asking his blessing, because during his last visit to our house the two of them disappeared for a while (I found out later that's exactly what had happened - my father was impressed and pleased!). I kind of suspected it would be that weekend, since he was running out of days before he had to leave for another far-away state to go to med school, but nothing had happened on Friday or Saturday.
So it gets to the last day of my visit and we're at his apartment. We had a lovely, totally geeky day together that day. We'd been watching my favorite sci-fi series together because I've been trying to get him hooked (and it was working), and happened to watch one of my favorite episodes - two parts. After the first part, we went out together for ice cream at the famous gourmet shop nearby and sat on a bench together just talking and sharing. We went back to his apartment and watched the second part, and after it was over I started to stand up from the couch, saying we should get ready for bed.
So THEN he kind of jumps up and says "wait, I have something to play for you."
I am instantly a little bit suspicious, but since he is a big guitar player this isn't too unusual. I LOVE hearing him play; it's a big portion of our relationship - the first day we met we bonded over our love of the same kind of music, and later he kind of chose "our song" when I asked him if he wanted my phone to play anything in particular when he called. It turned out to be a romantic, but not corny rock song, and it makes me all mushy whenever I hear it.
Anyway, he heads across the room to his desk where his guitars and computer sits and instead of grabbing his guitar, he gears up iTunes, sets something to play and comes back to me. I hear the beginning of our song, but it's just a little bit fuzzy, like it's been recorded, not from a CD. I realize quickly that it's HIM playing the guitar parts, and then singing, but modifying the lyrics to be about ME. Then he got down on one knee in front of me, pulls a ring from his pocket, and asked me to marry him. The cutest bit is that it had a little blue string from his pocket clinging to it!
I told him yes, of course, plucking the string from the ring; he slid the ring on, and the rest is history.
He had to record all of the guitar parts in the song (which he had never played before), and put them together properly (and sing, which he always says is not his strong suit, but he sounded great!)...He says it took him a couple of months to get it to his satisfaction. I made sure I snagged a copy of the recording on a flash drive, lol. It makes me happy to hear it whenever I think about how much I miss him...1000 miles away...sigh.
To me, it was perfect!
