Ringtones

My phone either rings or vibrates. I do not have have any flashiy ringtones that are a portion of a 50 or kanye's latest hit. I do not know why any one would want a portion of a song to be their calling card. maybe someone can explain this to me . As a teacher I am subjected to many ringtones on a daily basis and the conclusion that I have drawn is it says something about the personality of the cell phone user. As a teacher maybe mine should be to sir with love or president bush should use "hail to the chief " as his . If this is what ringtones are all about.I guess that is okay. What do you think
