I went grocery shopping with DD1 and 2, ages 2 and 9 months. I had my cart off to the side choosing some items on my side of the aisle (I'd guess about 2 minutes). There was another woman and her kid on the other side of the aisle, but I wasn't paying attention to them because I was focused on my young children and my shopping list. I needed something from the side of the aisle where she was standing and since her cart was blocking it, I said 'excuse me' so I could reach the item.
She huffily replied, "you were standing here blocking me this whole time".
I said, "you could have asked to move and I would have"
She said "you saw me here and knew you were blocking me this whole time"
As I said, it barely registered another shopper was there because I was not facing her because I was looking at the items on my side of the aisle and interacting with DD1 who was standing next to me and thinking about the groceries. I wasn't paying any attention to what she was doing. I was also very annoyed that she presumed to know what I was thinking. I then said "I didn't know you wanted to get in there", as I walked away and didn't hear a reply. I should have said "what an interesting assumption" because this woman assumed she knew what I was thinking. I tried to keep my voice calm and pleasant during this whole exchange. I also didn't want to further engage this person.
I realize my mistake in this situation and I should be more mindful of those around me (difficult with young kids, but not an excuse) so I realize I was part of the problem. I feel the shopper was being very passive aggressive in getting huffy with me when she simply could have asked me to move instead of inventing a scenario in her mind where I am deliberately blocking her. Since she didn't ask me to move politely, I feel she doesn't have a right to express her annoyance at me when I politely said 'excuse me' because she was blocking me. Also, should I have been gracious and apologized for being in her way when she first said I was blocking her or is an apology not necessary since she approached the situation in a rude way?
