If your friend or family are too stingy it is because of your relationship with them, Why must u start calling someone just because they travel abroad, The fact that someone lives abroad doesn't mean they are rich, some people are here on a visit or student visa and they have no right to work. how do you expect them to make ends meet. they have brother, sister and parent who are obviously closer to them than friends. they will always protect their interest first but in some cases they help people based on their relationship. If you have never been in Europe before please don't even say people are stingy. if some people look at what they are going thru they would not even spend a kobo on their parent. can u imagine urself licking some 65yr old woman pussy just to get papers. I'm grateful to allah my case is not like that but i pity people in such situation but God knows best. u cannot imagine how frustrated people are in this part of the world. if someone doesn't return your call, forget about them and work towards achieving your own goal. people only call u when they know you have positive influence on them. do not be bitter if ur friend no call and when u call them stop harassing them why them no dey call. one luv
