[RANT] Family doesn't understand the invitation. Or is it just too confusing

So my invitation said "Ceremony at 4PM". "Cocktail hour and reception to follow". Apparently many of my relatives are upset and confused that they don't know when dinner is. This is causing my parents to be upset that they are asking, and making me upset that no one gets it. A relative apparently asked my parents "what is the exact time that food will be served for dinner" and that the detail of what time the food, dancing, etc should be on the website.Is this normal? Did I make a mistake? Or is my family just too out of the loop to understand that when a ceremony and reception are in the same location, they follow each other... via /r/weddingplanning http://ift.tt/2ucFlQY
