About tall guys...again

Really, being short really has its disadvantages sometimes. Today it happened again...while going downstairs for lunch and while going back upstairs after lunch, I bumped each time into someone from the lab. While going down, it was fine...but while going up, this guy came down, I saw someone but didn't see who he was (that would have necessitated lifting up my head...at an angle well above the horizontal plane, shall we say?) And he said "bonjour".

And I looked up and saw that it was one of the guys I had worked with. Whew, at least there wasn't much hesitation on my part.

This can get pretty embarrassing sometimes. I should get myself a type of rear-view mirror...except that it should be a "high-view" mirror. Hmm...do you think there'll be demand for it on the market? Should I patent it? lol

(Again, I shall make the link later. This time I'm sure it exists. lol)
