SO, can you give us a rough "adjustment timeline" for those wanting to move here? Let's say they have rudamentary basic Spanish down (not DR Spanish) to start...care to make rough guess?
I know this comment was directed at Lambada, but if I may...
I don't know necessarily if language is so important because I understand that many expats are able to get along with much less than fluent. However, it is important to make contacts to call on when there are problems, such as lawyers, handymen, mechanics etc. These can be had typically throught friends, Dominicans or otherwise.
There will always be problems, due to inefficiency and general lack of ability to care for one's job as nothing much more than a means of getting a paycheck. However, this is greatly mitigated by the pace of life - one learns to move a a slower pace and accepts some inconveniences, because after all it is expected to have to take care of certain personal items. Furthermore, the great plus if one can actually get to the level of being fluent is that Dominicans are very friendly compared to Westerners not to mention very open too so meeting people is always a pleasure. The fact that one is a Westerner is always a source of conversation so it is very easy to keep one entertained, whether it be the gym, grocery store, pharmacy, etc if one is so inclined. I have found personally as my Spanish has gotten better that I seem to have less and less experiences where the locals just see me as a "source" of income and do whatever posturing they feel is necessary to get me to give them money.
Also, the fact that we have a local small supermarket and farmacy that have delivery for RD10, not incl the tip and I work in my home, we honestly don't have to leave the house a whole lot if we don't need to. In fact, my wife hardly gets out of the house except on the weekends to see the family. All in all life ends up being much less stressfull here. I have been here two years btw.
