This morning I tried to fix the leg of our coffee table while my wife did some Pilates on the rug next to me. I thought I could fix the leg by myself—and quickly. Well, it’s IKEA, so one thing after the other occurred and I finally had to ask wife: “can you hold ___ real quick while I screw this in?” She helps, and even suggests we flip the table over to get the screw. So, we do. As she clears the table off she gets potting soil from our aloe Vera plant on the coffee table (just a little). So I grab a sheet of paper and am about to scoop in the dirt and throw it out. She grabs the sheet of paper and says “give me that.” 
I didn’t want to drop the dirt, so I said “I got it.” She persisted and tugged on the paper. (I know this is like an exchange between two kids fighting over a toy #pride). She raises her voice and starts talking fast *TRIGGER ALERT* then she drops the line that triggers me every time: “What’re you doing?!” 
She lets me have the sheet, I scoop the mulch, she says “w/e, I’m just gonna shower.” 
I ended up feeling judged and criticized, so I did what I always do: Break something, clean up the mess, then leave for the gym. 
The IKEA coffee table shelf was the victim. Now, I feel bad about overreacting and am trying to think my way out of it.
WHY DID I GET SO MAD?
