there is something we do not want to do but we have no choices ,such as something happens nowadays.i am not willing to join a  play staff to act a role in a play,otherwise they force me to do so.to some degree ,i can not tolerate.in fact i hate others' forcing to do something i do not want.that's a problem for the reason that if i refuse them i may be push out of my class.i can not afford the result of my unresonable behavior.sometimes we turn turtle.
