I think I shy away from anything that might offend anyone.
Like this one time, at work, I am an insurance agent, and she comes in to pay for her policy, and she was blond, and we all know the typical dumb blond jokes and such, but she really was the epitome of a dumb blond, I was almost offended by her stupidity, and then she pulled out her check book and guess who was on it....BARBIE!! I had an A-HA Moment and it explained it all! I had a really funny post written in my head, but didn't post it because I didn't want to offend anyone who might just absolutely love Barbie.
My day 2 post isn't as funny, but it did help to define who I am.
Another thing I don't often post about is my abusive ex and what I went through with him, I know it hurts the hubs to read it and hear how I was treated, and I want my blog to be fun and happy, and that is why I don't often post about the cancer I am going through and about the fear. I hope that someday my boys will read my blog and find it funny, not full of horrible depression.
So I limit myself to these tear jerking posts!
