They grab one's armsleeves with both hands...then the 'shakee' feels compelled to put their gripped hand then the other hand on your armsleeves...thus contact, but no real contact...Maybe an 'airkiss', but no contact? Worth a try ???

And yes, the 'grip suspense' just holding onto a cup can be an adventure! I'm using commuter travel cups that sort of have some spill protection for the shakes and 'tilts'. I also use 'Duncan's Kitchen Grips' potholders for hot things when cooking or microwaving...they grip well on both sides, and do well [unless wet] at hi temps. I've had mine for 4 years and they're not deteriorating one bit..with lots of use.... They also work well for opening jars and bottles...I wish Santa could be delivering them to all of you!
