My friend is not your friend.
Your friend is not my friend.
So, u, seeing me talking to my 30+ years old fren using "aku hang, I You, saya awak" doesnt mean u may do so too.
Just remember, that person is my friend, have some respect for the age gap and please, dont just simply drop the formalities. If u're in position of having age gap with my fren, please, kindly address him/her as abang/kakak/aunty/uncle. We may be so close that we could drop the formalities but u, it may be a long harsh thorny road ahead.
Well, unless u, me and that person are already fren. That, of course is another story.
