See, I used to think that. But now I have a slightly more forgiving rule. My ringtone will never have words in it.
I'm not completely reactionary. My first cell used a song as tone for a week. I missed a lot of calls that week. My most recent phone had the default ring song for a day, because I didn't think the change it, after getting all of the other settings set. I almost missed the one call I got, but someone else thought their phone was ringing.
I'm from the age where phones rang. Apparently, I need retraining to function with something other than a bell. I won't say I've grown inflexible, because I haven't. But the technology allows me to make it sound any noise I want, and it's one less thing to worry about. I don't have any kids or other sentimental reasons to personalize the sound, and few enough people use ringing these day that I can be reasonably certain that sound is my phone. When it isn't, I know there's a kindred spirit near (or someone with a really old cell phone).
