Forgot Shower Strainer

Right now I'm bothered (admittedly from other things too) that I failed to put a strainer in the master bathroom shower.  I had swapped out the one that was there and put that in the master bathroom sink, and I was going to toss the one that was in the master bathroom sink because it was getting all clogged up.  Somehow, I forgot to grab a new one (or an old one -- get this, My Father takes the time to unclog strainers in order to re-use them.  Yes, it saves money, and I put one of those cleaned ones in the shower, but I feel like this is a First World privilege that we should indulge in -- don't scrape shit off of a strainer, they're only two bucks apiece!), and worse than that, I put the plastic strainer that goes on top of the strainer back where it was, as if I had already put that second strainer back in.

Worst of all is I don't remember how long ago this all was.  I think, though, that it had to have been at least a month, and possibly it's been longer than that.  Lord knows how much of my hair and dead skin was able to get through that's currently clogging up the pipes.  Dammit, man, how could I forget something like that?  I had an entire process I needed to do, and I just stopped halfway through it.  What the hell was I thinking?
