I was hanging out with my friend the other day when her phone rang and her ringtone was "River Flows in You" by Yiruma.. and for some reason I almost felt offended because I think of it as MY song. I walked down the aisle to that song, so it has such a special meaning to me!! Haha I didn't say anything though, that would be crazy!
I feel that way about a few songs. I was really mad when my then-bff used me and DH's first dance song as her first dance song, my wedding had only been two months earlier. I was really upset about that. We're not really friends anymore so I guess it doesn't matter.
