I know how you feel. My husband had a friend from grad school, who was in need of daycare for his son. Because he was an old friend of my husband I said ok without much thought. Well they were never on time and got all up in a huff when I asked the for there late fee. This went off for some time; I didn’t do anything because his son and my son seemed to be getting along great. But finally I had to tell them to find care else were. It took me three months to find another kid and believe me cash was tight for that time. But I am so glad I did. It is tuff when the child is sweet but the parents suck. Have a nice hot bath a glass of wine and hang in there.
