So, there's this thing from the Aruch Hashulhan instructs you in the "Jewish" manner of tying your shoes. For those of you who aren't familiar with this, you are supposed to don the right shoe, don the left shoe, tie (or in the case of my boots, zip) the left *then* tie (zip, velcro whatever) the right.
When I got home today the right boot was unzipped. That means I had one unzipped boot for about five hours. I'll be alright... I thought I had more kavanah than usual davening today... I suppose it came from the lack of kavanah while donning my shoes.
