When did I turn into a big fraidy cat?

Hello,
Today I an feeling a bit insecure. I have a playdate with a woman from the boys pre-school today. Funny, how it became my playdate. The boys have a playdate with twin girls. They are very sweet and cute, the boys call them their girlfriends. We were invited over to their house a couple of weeks ago and had a great time. Their mother seemed as nervous as I, so I felt more at ease. After a while I realised that we have a lot of the same anxieties. Worried about our husbands jobs, about someone bullying our kids, staying sane in the midst of all the craziness that is happening in the world. They are coming to our house today....do we have enough stuff to keep the girls entertained? Do I know where everything is? Stuff gets put away in verying places sometimes....Anyway, gotta go...
