It can get worse than that, trust me! My wife and daughter were in fine feminine fashion one day, a tandem of irrational estrogen unleashed. I felt the walls of the house closing in on me, so burst outside praying to see a farmer on a tractor, a big diesel truck, a muscle car...anything even remotely male-oriented.
Then my little boy came running out after me, dressed in his sister's high heels, leopard-print leotard and matching mini skirt...with a purple wig on his head.
It was all I could do to not impale myself on the garden rake /forum/images/%%GRAEMLIN_URL%%/shocked.gif
Oh, by the way. Many congrats on the girls! I wouldn't trade mine for anything /forum/images/%%GRAEMLIN_URL%%/cool.gif
