When will he meet with Trevor? Why are their goods late?

F：When are you coming back from the conference?
M：I’m flying back on Monday，late in the afternoon．
F：Remember you are meeting with Trevor on Tuesday morning!
M：Oh，could we reschedule the meeting to Tuesday afternoon，because I need to get some materials ready in the morning．
F：Ok，no problem !

F：Unfortunately，this time of year is often troublesome for goods delivery．
M：Why is that?
F：Well，there are weather delays and shipment delays．Sometimes，larger packages are delayed because of a bottleneck at the distribution point．  
M：I see．That’s why they called from California that the delivery of our goods was postponed due to high waves caused by strong storm．
