getting groceries and getting ugly

Growing up my dad did all of the grocery shopping. In fact, he still does the grocery shopping. He is one of the only men I know who can be trusted to actually stick to the list and not come home with donuts, chips and some random type of meat. Of course, if there is a sale on ice cream then all bets are off, but for the most part, he goes in and gets what my mom has asked for.
When I was little, I would go with him to the store. It was our fun father/daughter time. I felt so grown up and helpful and I loved having my dad's attention all to myself. 
I'm not sure what happened but at some point I began to really dislike going to the grocery store. It became this huge time-sucking place that attracts the slow and the oblivious like moths to a flame. I'm all for taking your time and enjoying life. But I admit that I get peeved off when I get stuck behind someone who is shuffling through the grocery store and counting out change from their embroidered coin purse.
 And I definitely have an issue with the oblivious people. You know who I am talking about. The ones who park their cart in the middle of the aisle and then wander off to look at something ten feet away. A few weeks ago the woman in front of me struck up a conversation with the cashier. No problem. Except that she continued the conversation after she had already paid for and bagged her groceries. Did I mention that she was still standing in the middle of the lane? My groceries were already headed down the little conveyor belt and I couldn't even push my cart through. I said, "Excuse me please." And she looked at me and said, "Oh, did you want me to move." I replied, "That would be nice." And she huffed off. All she had to do was move out of the check-out lane and continue her conversation there.
The grocery store brings out my ugly side. The side that is impatient and judgemental. I don't want to give grace to the lady with her cart blocking the entire soup section. I don't want to wait behind the mom who is letting her child count the number of marshmallows on the Lucky Charms box. I just want to get my stupid groceries and go home.
In case you were wondering, I just got home from the grocery store before I started writing this post. I apologize for the ugliness but I promised to be honest and this is honest. This is me being ugly and small. It happens and I'm learning to notice it in the hopes that I will, one day, be able to change it. Today is not that day.
