Three floors up

Pickle and Pearl wanted to take a look at some of the crowds of people that gather in places of commerce. So I (the 'guide') took them to a local Mall to see what they could see. As I explained to them,in December I tried walking to get my total K's for the month but the crowds buying Christmas presents hampered my progress. There were wall-to-wall shoppers. Today the shoppers were scarce on the ground, I could have run (some hopes?) without bumping into anyone. I told P. & P. I wouuld bring them back at a more seasonable time of the year. Pearl said "Don't worry I am having a great time riding down the handrails and flying back up to do it all again"
Meanwhile, LITTLE FLY upon the post/ Who do you love the most?/ I'll bet you are thinking, "It is me/ But I'm glad that I am not a flea".
