What will you do with opportunist relative?

Well that sounds disgusting and frustrating as well. But it happends; people tend to be ungrateful for the past favors they had from somebody who cares when they don't need help anymore. Well sometimes it teaches us lessons. So maybe the next time that they will be approaching you for help, you may remind them of the pain you felt by being neglected (by them) when it was your hard times and you needed help. However, as Filipinos I know that it's not very easy to do or talk like that considering that culturally, we are very reserved on our feelings; trying to protect the relationships and in an effort of doing so we suppressed our anger and frustrations. Maybe what you can do is to refuse them (next time) telling them you have your own priority needs to attend to because you realized that nobody helps you when you are in need. That is a blatant hint for them and am sure they'll get the message.

Oh!! that is very aggravating. I know I will lost my patience too when it happens to me. Maybe I should be vocal and frank to them. They should know that it hurts me when they do that. Well, if they ignore me when I told them what I feel, the next time they come to me again, I will also ignore them.. hahaha

I try to avoid them as much as possible. It's no use fighting especially if they think they're always right. You're just wasting time and energy on negative people and it's exhausting.
