True story: My brother and I tend to go out in sympathy when the other is not feeling well. Remember the insomnia thing??
Anyway, the other morning he rang me bright and early to thank me for sleeping well the previous night.
He then proceeded to get up me for the days prior to that when he felt like shit.
After I told him I could hardly be blamed for getting my period, his immediate and somewhat indignant response was there was no doubt in his mind that if he bled he would be in sync with me.
God, he makes me laugh and laugh.
