Unwanted Advice

Have you ever received unwanted advice from someone? Don't you just hate their smug, self-satisfied words, their torrent of better-than-you knowledge flowing unwelcomingly into your ears despite having made no request for their advice? Well, today I made the most unpleasant discovery. I am that awful person. Oh horror of horrors! I am that delusional idiot spouting off completely unasked for advice to tortured individuals unable to escape my egotistical rants.
Today's victim? One of my very best friends. Poor thing never even saw my e-mail full of relationship advice coming. What can I say? As my sister tells me, I was born without a filter, which means I say/write things that get me in major trouble without thinking. The problem this time? I really thought that I'd well, thought it through. What I didn't consider was the fact that I had absolutely no right to give her advice in the first place. Oops. Now, I'm left trying to fix my terrible mistake. Unfortunately, she's incredibly offended (and has every right to be) and I have no idea how I can put it to rights.
I just can't believe I'm that person. I always thought I did such a good job of not being that irritating advice giver, but now that I look back on it, the evidence is clear. My husband would make a star witness if this were my trial. He'd be able to bring load after load of incriminating evidence, showcasing my bossy, know it all tendencies. (Although I usually give myself a pass when it comes to him. He's my husband, he has to take it!) My sister is another casualty of my abundant advice giving. The poor thing's spent far too many an hour putting up with my lectures on all things I have no right to give advice on. But this time a good friend has taken the hit of my irritating habit, and I know I've gone too far. I hope she can forgive me, because in truth I couldn't possibly be more contrite. I feel like an idiot (probably because I've been one) and I don't know what to do.
The first course of action is clearly an apology, oh ever so many more apologies. For the second I'm considering getting my husband to sign off on everything I say and write. He's a much better judge of what's appropriate than I am. And thirdly, I think whenever I feel the need to give advice, I should write it down, read it over and then burn it. Burn it into a pile of smokey ashes and walk away. Because advice unasked for is just harassment.
