Waving

I took a bus yesterday.


When my bus stopped at the signal, one small truck in the next lane also stopped.


There were 3 men inside, they saw in my direction then all started waving.


I looked back because I thought someone was behind me, but no one was there.


One guy pointed at me and waved to me again!!!


???Have I met them before???


I waved back to them (just in case?!) although I was not sure whether or not I knew them.   (~.~)#


It was only for 2 minutes.


Strange Experience!!!
