Sorry . I didn't mean to be late . Can I come in ?   What's your excuse this time ?   Have I used the one that my sister is sick ?   Yes , twice last week .   Are you sure ? I thought I said it was my mother .   I don't think so . But it could've been .   Well . You can trust me this time . My sister is definitely sick . I'm just coming from the hospital . They say she might even die .   I don't buy your story . Try not to have any more sick relatives this week , all right ?
