Honey is your mom home????

I am getting really tired of hearing this. You wouldn't think a 33 year old adult would get asked this on a regular basis while answering the phone. Ok, I KNOW I have a young sounding voice. I even know that to some people I have a young, irritating sounding voice. (Thanks again to the guy who pointed that out 10 years ago at a bank I worked at...Oh, and BTW, I am not a bit self conscious about it....) But, you would think as the years go on....I would sorta get a more adult like voice. Nope. I think all hope is gone. The funny part is, I don't hear myself as having a child-like voice. Maybe I am in denial. My grandpa has called our house and after talking to him for 20 minutes I realize he thinks I am Danielle. Then I don't know if I should just play along, or break the news to him gently....
So, today I answer the phone, as I normally do, because I am usually the only one home during the day, and a lady on the line goes..."Honey is your mommy or daddy home?". What the heck should I say to that? I usually say something like.."I AM the mommy..". But I really considered playing along this time. I should have went...."No, my daddy and mommy aren't here now....they left me here alone over a month ago....they said something about going to Vegas with their tax money.....but I haven't seen or heard from them since. Do you have any food???".
Gosh, I am just getting tired of it. I mean, I think I should probably just accept the fact that my voice may not ever change. But I need to log off now, and continue practicing my new low-adult-style voice.
