Bob , would you come and help me ?   Of course . What do you want me to do , Mom ?   Could you hold these packages while I look for the key ?   Alright , what's in them ? They are so heavy !   Just things we need for the picnic tomorrow .   Well , hurry up and open the door please . I told you these things are heavy .   I'm sorry , but I just can't find the key . You must have it .   Oh , yes , it's in my pocket . But how can I get the key while I'm holding all these bags ?
