Don't be Stupid You Know I Love You

I say some pretty stupid things without meaning to. Sometimes things sound good in my head, or funny then I say them and I'm like wow that was horrible. Anyway, I was at walmart the other day buying ice cream and the cashier said enjoy the ice cream. Gues what I said YOU TOO!! He just looked at me and shook his head. What do you say.
On Sunday, My grandma had passed away and at church I did great no crying or anything until one of the older sisters said she was sorry. Then the tears start, well I am not a cryer. In fact I try really hard not to in front of people but here they were. I'm trying to look happy and smile with tears running down my face, I finally get the tears under control and am talking to my aunt and another sister walks up and points to my eyes and says it looks like your having issues today. I thought she was kinda trying to make me laugh and I was a little annoyed at that thought and I popped off and said "my grandma died this morning." I could tell immediately that she didn't realize and I felt horrible.
Another time I went to see my sisster she was having a baby. She made us all lunch(while she was in labor I might add, she also made a quilt block and did her laundry yeah while in labor)and we were in the kitchen cleaning up and I was standing by the counter and the re wasn't enough room for her to get through and she said something about being fat, so then I said why don't you go lose some weight. Then I went in the other room and tried to convince myself that hadn't come out of my mouth. What I was intending was go have your baby and then you won't be as fat, but even that sounds horrible now.
Anyway my point, yes I have one. If you happen to find yourself getting your feelings hurt by something I say please understand I really don't mean to. I am really not a mean horrible person. I just can't talk and walk at the same time yet LOL. No really, it sounds funny before it comes out of my mouth I promise.
