How do you usually handle this situation (details inside)

You’ve spent a good amount of time (3 days) with a particular group of people. You all were apart of the same event. In this case, a visitation and funeral of a loved one. A loved one whom you all were really close to. By the third day, you’re emotionally (and physically) spent and having a convo with the group is tough. You have a bit of chit chat, then there’s those awkward periods of silence. In all honesty, you don’t feel like talking anymore. You’re with the group, sitting around and at times, no one is saying anything. Sure it’s awkward, so, eventually someone feels the need to say something. Why? Why can’t there just be silence for awhile. I know for me, although, usually quite talkative, by the 3rd day I was pretty much done like a dinner.

I came back yesterday and I’m still tired.
