My friend got mad at me via text. He said I'd told him that 50 times this winter and some in the summer and he was leaving to sit in his spa.

OK what did I say? "I'm cold". I get cold when I drink a protein shake, especially at night. He thinks it's just because the milk is cold but regular milk doesn't do this and neither does water. So this is what I was trying to say to him but he just got miffed that I said I was cold "again". I literally tremble for 15 minutes after I drink one.

What is my friend's problem anyway? Maybe he just has no answer and that bugs him?
