Hi-5 Red Queen Syndrome

I talk with the Hispanic gentlemen from housekeeping periodically and he seems to latch on to various mannerisms and the most recent was me giving him a thumps up as a way of illustrating my emotional state. Normally, I have an obligatory hello in the morning, once around lunch and possibly on the way out and each would solicit some sort of response. Now, he appears to be seeking me out to get a thumbs up. On Monday, I gave him a single thumbs up, and by Thursday he could only be sated with two double thumbs up. I fear by the end of next week, 60% of my day will be spent giving him a thumbs up. I will have to run faster and faster to stay in place.
