airport coincidence

arriving back from holiday(from italy) i inadvertantly picked up the wrong suitcase,only realising once through customs,i waited for the people with my case to come through, a couple of dear old ladies who were confused but understanding! (i,d seen the ....son part of my name on the red label,the case i,d picked up was identical to mine the red tag was the same and the surname ended ....son. the following year (approx 13 months) i was once again waiting for my bags (having arrived back from italy) same airport and was about to pick up my suitcase when i realised the surname was different needless to say the owner was the same two old ladies! who looked at me ,not sure they realised it was the same person who had picked up their suitcase by mistake a year earlier.
