Family Time

Hemi's father is a mail carrier. After he leaves home, Jett arrives and gives the package to Hemi. Also, Jett gets permission to go to Hemi's primary school and to have dinner with her family. After both Jett and Hemi entered the restaurant, Hemi's father phoned and said that he would not make it to dinner on time. The reason: is he has many letters and packages that need to be delivered. Jett volunteers to help him finish mailing the items. Does everyone get to the restaurant for dinner on time?
