Cutting Me with Words!

Read the text exchange below between my two children, nothing like making me feel like shit! You know how words cut like knives my son sure as hell can just cut me to shreds. He asked my husband and I to go to a college football game down in Orlando this Sat. which is said to be cold. Now can you imagine a 2-year-old who never sits down at a football game it will be a nightmare. I told him we didn't want to go, well he gets all cranky and nasty. I would never talk to my mother the way he talks to me. He wrote my daughter ranting and raving about me saying I never want to see the kids or do anything with them. I understand he is just trying to do a family thing but what the hell, going to a football stadium with a 2-year-old????? It will be a mess and that it was all the way down in Orlando is a no win. I will have to deal with his wrath for days now. Am I a terrible grandmother? I am sad that my son feels I have let him down, but you can't get mad when someone does...
