yes, hold this..

u can do something or what other people want, but u don’t want to do this..

otherwise, u want to do something or what other people want, but u can’t to do it..

got the point?? not yet?? hmm..

example: u can do your homework, but u don’t want to do it because some reason like u are lazy, or u are sick..

u invited by your friend to going somewhere, u want to join but u can’t beacuse u have a lot of task, u have to take care your mom, or else..

see??πŸ™‚

so, if u can, u have to want it and otherwiseπŸ™‚

its just my point of viewπŸ™‚
