I partially agree that the writer has left us in no doubt that the girl is just part of Rosie's imagination. The writer effectively portrays the girl as only visible to Rosie as Cara seems "unfazed" by her presenve. This verb implies that Rosie may be hallucinating the gril. ALternatively, perhaps Cara does not notic the girl as she is focused on moving along the row of plants. Furthermore, the writer portrays the gril as secretive as she does not want to be seen by Rosie. She is described as having "her back to Rosie", implying that she does not know Rosie is looming at her. Howeever, she then glanced over Rosie's shoulder with a "quick" movement "as if she were scanning". This use of simile may suggest she does not want to make eye contact with Rosie. The verb "scanning" makes the girl seem almost robot-like and inhuman and therefore this may shock us and make us wonder if she is a human. The adjective "quick" reinforces how she is afraid to be overlooked and therefore implies that she is not supposed to be seen, perhaps because she is a ghost. The writer may have done this to foreshadow her disapperance when she notices Rosie. Moreover, the writer successfully portrays the child as ghost-like and inhuman. THe wooden fences are "too high for a child to climb" and therefore implies that the child must have used some supernatural power to get into the garden. Her ace is also described as "pale" which suggests she may be feeling unwell, perhaps because she is ill. Hoever, this adjective "pale" also reminds us of a ghost's face which suggests she may be a ghost. Additionally, the child is described as "like the darting of a mouse". This simile reinforces the diea that she has some supernatural power as a human child cannot move so fast. The writer may have done this to suggest the child is only Rosie's imagination. Also, we may not be surprised by the child's disapperance as we kno that it is able to move extremely fast perhaps with her supernatural power. However, the writer portrays the child as poor and dirty in order to make us understand that perhaps she is afraid of being overlooked because she is ashamed of her unpleasant appearance. The child's hair hung down in a "dusty-looking" plait and her clothes are in "greys". This im[lies that she may not want to be seen as she has no clean clothes. Also, the writer portrays the child as strange by describing that she looks "older" than a child. This implies that she may have some diseases that make her look older than her age and therefore she does not feel comfortable being looked at by Rosie. Alternatively, perhaps the child is actually an older adult pretending to be a child. This explains why she does not want to be overlooked as Rosie may notice that she is an older person. The writer may have done this to suggest that the child is not Rosie's imagination and that the child is simply an older person in disguise. Therefore, we may be shocked when she disappears.
