It actually depends on the lifestyle of the family. Sometimes, they don't understand how complicated and hard life in the UK can be and can get. All they know is the xchange rate of £ is more than one peso.
If you spoil the family, let them feel that you have money even though you haven't then they will assume that they can get and have whatever they want. It is sad but it is reality. If you haven't got the guts to say that we don't earn gold everyday then some will take advantage.
We also have the attitude of make do and mend. Whatever came to our table is a blessing which is really good. I'm lucky to have a family that understand my situation and support me.
I contribute payment for bills at home like the net, half of the rent which my husband promised them and electric which is less than £100. It is only because my daughter consumed most of it so I pay for it which I think is reasonable.
Unless you say stop and you put a stop on it, it will go on and on and on.
