If we want to do charity, then we have to be playing and clean in doing this, what's the essence of doing good and later standing in the gap to receive back the same reward for what you have done in the past, what if the child later discovers that she is not even infatuated with you at last?
If you are also a gambler, then try to be a modest one and don't try to gamble just to impress others or have something as an intention to get as a reward at the end of it.
If you are training your wife in school, that can be a reasonable adventure since you guys are family and can start growing children with time. If you have it marry a woman and you are training her in school, have you ever thought of her leaving after she's done with school? Live can be unpredictable and it is better to take precautions than to try and make stupid excuses with regrets.
It saddened me when I hear about how my gender received tuition fees throughout their education and even money for up keep from a struggling man with the intention of marrying her after her graduation yet they'll refuse to stick with the agreement or at least tell the person on time to stop because they're not interested in marrying them. I find this act to be open fraud and this eventually will cause rage in the heart of the man after being denied the only thing they request off their efforts to make the woman a better person. I feel sorry for those men out there, and I assure you karma will always find a way to hunt those evil creatures out there who are pioneer of this evil act.
If I placed myself in the shoes of any man, I will not engage in anything that resembles such agreement, that means I'll not make such investment in any woman that's not my wife.
