i've been here for almost 16 years and although i've met so many people, and made some very close friendships...they are VERY difficult to maintain. hk is such a transient city (for expats) that just when i think i've made a great friend, they up and leave! (i mean, how dare they?!?!?! LOL). it has happened at least 4-5 times over my time here and it really gets exhausting finding the time to be able to meet new people and pursue the friendship. that mixed with thanka's observation about mixing with different financial brackets...extremely difficult when you are on the lower scale, moreso than when you are in the top bracket. i still have friends from all tax brackets; from people who work for their church (friends from church have given them a good deal on rent) to someone who is a house-husband (wife's work provides $70K+/month for housing....)
it can be frustrating, exhausting etc...but if you have time on your hands, then i'd say make the most of it! forget working...being pregnant already plus your VERY extended mat-leave requirements would make it virtually impossible...use your time to get out and about... join clubs, take classes, take up pregnancy yoga, children's first aid (preparing for your new arrival)...whatever your heart desires... you just may meet some very interesting people along the way.
