Friends want to get fat!

Whoever will expected... I actually have 2 girlfriends who wanted to gain their weight so desperately...=.="
(Girls, please kill them, no need give me face)

Who are they??
Picture below: First and Second from left (those who want to gain weight)
First and Second from right (those categorized as normal-fit group =D)

Girls everyday complains "god! I'm Fat!", " I want to keep fit", "Do you think I'm Fat?"(leads to man's frustration)
These two girls complains "I want to gain weight!", "frustrated over everyone who asked us why we so skinny", "How to get fat?","why i eat so much oso cannot get fat wan?"
While they asking us, the normal-fit group, normally we would answer like: "eat more", "eat more fatty things"
For the next thing we saw while having meals with them, their plates filled with left over food.....=_="
ok la, i have no rights to advise them not to waste food, cause I normally do that, or else I stuffed my left over to my boyfriend. wakakak...
but whenever i'm having meals with them(mostly la), i clear my food.(so proud like tat)
Their weight is like less than 45kg!
Wind blows, they will fly away!
Macam malnutrition's people. 

Then they keep complaining, why I cannot get fat...
and you feel like punching them LOL
Writing this is not that I get annoyed by their complains
I'm writing this because I feel that this is the most rare case happens among us, the females.
I'm writing this also need more comments on helping them gain weight.
**note: they had tried those gain weight milk powders,watever junk food, fast food, but no use. some sort they have big worms inside their stomach...swallow whatever food they ate!hah!
