Careful with people

A coworker was friendly today, but I don't trust the friendliness. She is a crocodile with a smile. She is constantly finding fault. I asked my husband if he wanted to go grocery shopping. Before we went to the store, we went to an inexpensive restaurant together. We bought the groceries for his birthday party tomorrow. He opened the trunk and when he saw my mother's walker, he said, "What is THAT doing there?" I felt that his tone of voice was critical. I told him that I had driven over to my friend's office, but she was not working that day because she was attending a funeral, and I would go back on Wednesday. He also saw that I had charged items at the flower shop and when I told him it was a birthday present for him, he said, "I don't need a truck with flowers in it." I would never consider getting him flowers because he wouldn't appreciate them. I can't be around people that are critical, demeaning and insensitive. I was telling a customer that I am most comfortable around animals, cats, dogs and horses because they can't talk. 5 weeks ago today, my mother died. Since then, I have had stomach pain, am so sensitive, I cry if someone says "boo, worry about my dad and eldest daughter, and can't get along with anyone because I get upset. Oh joy.
