Twins?

Lizzi and I have often been taken for twins; despite the fact that we are 4 years apart in age. I always thought this a tremendous compliment since she is so beautiful.
This picture was probably taken three or four years ago. We also sound alike (I think all us sisters do) I have on numerous occasions pretended to be Liz on the phone. I have also used her 4-H I.D. to get into the county fair before... dishonest? Yes. But, I am being honest about it now! I just think it is crazy that they could believe we were the same person. It is kind of funny that we have younger twin brothers and I think Lizzi and I have done more switching then they have. Unless they are so good that we have just never known...
