The sentence should read "Mary eagerly offered to do all of the housework." And yes, your interpretation of offer in this sentence is correct :)

"Any businessman in Asia today will say that competition is cut-throat, not only between retailers, but among manufacturers as well."

No regrets for any choices you make:

Whichever option you choose, there can always be regrets. Once you have chosen something, just believe in it and keep going. Take whatever comes from it, the good and the bad.


I believe that what will be, will be. I think that putting effort into something or someone is a great thing, but I also try not to put in so much effort that I cannot deal with it.
