It was cool to be so young and carefree and spontaneous

You still look not that aged as you say.
In fact, i find you more active and cheerful than most of the young people now a days.

Adults there days are not that carefree as i used to see around me when i was a kid.

You are one active grandmaa out there, too young for that seriously.

Keep in touch with your old friend, it's always good economically to have a friend with dollars(i mean a rich friend:p)
