(actually it’s a proverb)
A rolling stone gathers no moss
People who are always moving, with no roots in one place, avoid responsibilities and cares.
“David’s in his mid-forties but has very few responsibilities, I guess he’s always been a rolling stone”

I sometimes feel like a measly rolling stone. I wish I felt at home where I’ve lived for 12 years and set up a small business. 2012 may see the turning point I’ve longed for š Happy 2012 !
(perfect sentence) Happy 2012 to you too, Marie!
This 2012 arrived bringing my forties. Now that rolling stone life comes to an end and new challenges appear in this new year.
God bless you always, Emily.
Good to see you here Oscar!
(just a note, we’d probably just say “…this new year” – without “in”)
No more life of a rolling stone for you any more?!
Thanks a lot, as usual, your help is fantastic.
Many people think this proverb comes from the Rolling Stones (band), but in fact they took their name from the proverb.
