Vicente is a caring boyfriend, so when his lady's friend passed away, he wanted to cheer her up. While The Purge isn't necessarily an uplifting tale, he thought it would take her mind off reality for a couple hours. Unfortunately for Vicente, the phrase "viewing" can refer to both a movie time and a—well, you probably see where this is going.
The first text seemed to cheer her up.
As you probably know, the "viewing" in regards to a funeral is the time for family and friends to gather around and look at the deceased, usually in the coffin, at a funeral home. And a "viewing" of The Purge is a fun outing to the movies.
The next round of texts did not cheer her up.
As a Reddit commenter noted, "yours is an honourable cringe, Vicente. You are a bad man, but you try to be good." Hopefully his girlfriend sees that, and eventually goes out with him again when she's done showing that text to everyone and calling him an idiot.
