My bun bun is the same as your friend, over 10 years in HK and nearly 50. She is a bit lazy and always sit on sofa carring my 2 years old son watching TV when we are at home.
only come for 2.5 months, the first month is ok, very lazy and always sit on sofa start from 2nd month, talk to her strictly and will not do that when we are at home only.
