When I read that, I immediately failed safe and assumed a touch of sarcasm.
Mind you, I'm 47 and compared to some programmers I know of - I am still young (yay!) I reserve "get off my lawn" for those who still snigger about making doilies out of punch cards.
Don't want to divert the conversation but in some of the circles I've been mingling lately, 35 in software engineering is 'get off my lawn' domain.
