Time to open the presents. There are lot of them. Lets compute. there are 4 + 3 + 4 = 11 people here. lets say that each person gave a present to each each other person. So is 11 * 10 = 110 presents. Lets say it takes 2 minutes to open each present. That is 220 minutes, almost 4 hours. Yikes. But well worth it.
