Two bits of advice, the second of which may or may not be based upon actual events:
The phenomenon known popularly as "brain freeze" is completely avoidable, as I have explained many times to my children, who ignore their mother's counsel and suffer as a result. Here is what you do: Take a bite of your ice cream, or your Slurpee, or your water ice, and hold it in your mouth for a few moments before you swallow it. Your frozen treat is then slightly warmed, so that when you swallow it, your brain stays at room temperature.
If your wife or significant other is explaining a series of events, you should avoid instructing her to "stick to the facts and don't give me editorial comments". Because I promise you that she will respond to this instruction with a far more lengthy and opinionated editorial comment than you would have received had you just allowed her to tell the story her way, thankyouverymuch.
Additional unsolicited advice will be offered occasionally, on an "as-it-occurs-to-me" basis. Meanwhile, feel free to submit your pressing questions in the comments, and I will do my best to provide personalized advice.
