Is this wierd...?

yesterday at lunch i was sat at the table at work with a work mate. i think hes about 38, he's married with kids. and i had a twitch in my leg and accidently nudged him. and he goes "oh... well if u wanna play footsie, dont worry i wont tell the wife" haha. he was only joking and we just laughed but then just now he ped me in the corridor and he said"if only u were a little bit older". is this wierd?!?!
