“When I was your age, there was no TV/computer.”
“When I was a kid, my parents were not as liberal with me as I am with you. *Mind it* “
“My parents never pampered me the way I am pampering you.”
“You want a bike/car? When I was young, I used to travel 28435 kilometres by bus. Or walk! *Ominous look*”

“Why do you need a cellphone? When we were in college, we did not have cellphones.” (one of the chief reasons for banning mobiles in college. “If I didnt have one, like hell you will be allowed to keep one”)

People who oppose the Western influence on Indian youngsters may say -

“When I was your age, I did not have a girlfriend.” ( “I didnt get any in college,so I am not gonna allow you to”. Of course, it could mean, “no girl ever wanted to be my girlfriend”. Hmm, I could actually empathize with such a guy.)

And of course,
“I miss the good old days. Things were so much better than they are today.”
Yes, too bad things arent the way they used to be. We could all be dressed in animal skin and go
