after i left singapore i used to accept friends request from ex colleagues thinking why not i used to worked with them right.
then i realise after few days or weeks later they unfriend me.
i been thinking why like that then i come to conclusion that they only add me is because they want to see how i am doing in Australia and after they see my facebook photos they dissapointed that i still doing well and unfriend me lol.
but there are some ex colleagues i still keep in touch till today they are very humble and very nice people to me they are part of my family.
