I'm sure my sister is no different to anybody else's. She's reasonably happy to wander about the house in her bra and knickers, I suppose she doesn't really see me as being male for I am two years younger than she is. On a couple of occasions I have even caught her walking from the bathroom to her room wearing just a large bath towel around her waist and a smaller one around her wet hair
