To be sure, only children experience some things differently from those with siblings (兄弟姐妹 ). Many feel more pressure to succeed. In the absence of brothers and sisters, only children are also likely to look more exclusively to their parents as role models. In India, 19-year-old Saviraj Sankpal founded a support group for the tiny number of only children. Among other things, the group does volunteer work to be against the myth (神话) that they're irresponsible (不负责任的). 'People think we're pampered (娇惯) and spoiled,' says Sankpal, a computer engineering student. 'But I'd like to remind them how lonely it can get.' Most only children, however, say they wish for siblings only when it comes to caring for aging, unhealthy parents. Britain's David Emerson, coauthor of the book, The Only Child, says that such a person bears terrible burden in having to make all the decisions alone. Emerson knows from experience: After his father died, he chose to move his elderly mother from their family home, where she was vulnerable (易受攻击的) to house breakers, to a new one with more safety, 'The move was quite hard on her, and she might feel that I pushed her into it,' he says. 'Finally, I am left with that responsibility,' In the future, more and more only children will likely face similar choices. With working mothers increasing, many families are finding they simply don't have the time, money or energy'to have more than one child. As only children become common, perhaps the world will realize that the accusation (指责) made against them is unfair. It can be inferred from the passage that only children's parents should______.
