Well, I brought up the pending issue of "friend time" with the man. All attempts to couch the discussion failed. I asked him to hear me out before going on his guard, but of course, he was defensive from the get go. There were many words put into my mouth and I didn't get around to saying what I wanted to say until approximately three hours after the fight started. There was an interim where I was confused as to what the hell was going on and I had actually begun to think that I had overreacted.
Finally, I remembered and was able to say "I intended just to ask that your friends, who have a lot of free time in comparison to us, would be more understanding of the limited time we actually do have when we can be together. My hope is that they will think before calling and inviting themselves over after having spent the last five days at our house." This statement led to the man's apology for overreacting and not letting me speak my piece before he took things out of context.
In other news: I went to bed at 11PM feeling fine, but woke up at 2:30AM barely able to breathe through my swollen sore throat and due to my burning, congested sinus cavities. It looks like along with an apology, the man has given me a raging early autumn cold. Yay.
