I took part in road runs of 10k or half-marathon often before 65.  Each time the sponsors of the activities will give away a T-shirt or a tank-top to the participants.  So, I have amassed a lot of those "sport suits", but scarcely would I wear them during outside excercise because I don’t like those ads printed.  (Now I can only do walking, no running anymore.) 

Yesterday afternoon as usual I went out for walking.  In hurry, I could not find the shirts I always wear.  So, I randomly picked up one of my brand new "souvenir" shirt and went out.

when I walked around the peripheral trails around Duhu Park, suddenly a guy yelled from my back and said, "Wow, you are wearing the shirt of 2004!"  Then I found it is a Caucasian runner. and he said he also joined that running, too, so he recognized it at first glance.  Then he was running away, fast.  (I also admire his fluent spoken Mandarin.)

When I got back home and took off that shirt, I found no "2004" showing on the back. Then I found there is a small "year 2004" on front, though it is too small to be noticed.  Oh, my goodness, that guy is a real runner!
