Back On Track

I was running in the gym tonight, over the last forty-five minutes there was a 'yoof' in front of me who kept looking in my direction and making eye contact.
Initially I thought he might be nervous in case I remembered him from Crimewatch. He continued to look at me and make comments to his mate, comments I was oblivious to with my headphones on. Never one to jump to conclusions I assumed when he got on the running machine next to me that he was practising his 'getaway' techniques.
Imagine my surprise when I went into the changing and saw my shirt.
Never had 'Joggers Nipple' before!!
At least I now know what he was looking at!!
