Business is business

Growing up I had a relative, this person had offsprings, they would not ask each other for favors or do things for one another unless there was something in returned involved.
That was something I couldn't understand because when I do something for another being I do it selflessly. I see someone struggling and I feel the want to take on that struggle or problem and fix it, make it a better situation, make the stress of it go away. I do anything and everything in my power to help, to fix, to make their worries or problems disappear, I do it sometimes anonymously,  because I don't need anything from those beings, no acknowledgement, recognition, nothing in return. It could be because I never put myself in situations where I need anything from anyone, it could be because I'm a fixer, I've been called that before. Whatever that means hahaha. Or maybe I just don't want to be stressed hearing other beings problems they've gotten into. 
Back to that relative, she would always say " business is business ", and no excuses.
I've noticed a few beings try to get close to me and maybe I am as innocent or pure hearted as some say I am, but I think the word is gullible. I've seen theses beings be nice to me to get what they want then when I can't give any more they go away until the next time I have something they want. I have turned a blind eye to these happenings and I've given and gone without but I'm a simple person so going without for me means not buying a new mascara or frivolousy toys, they have promised to do things for me or feigned interest in me but never come through, naturally I never expected anything so there is no disappointment, I need nothing done that I can't to myself. Lately I've seen these beings come around and ask for things from me in exchange for little chores or things I can think for them to do for me so they feel like it's not a hand out but it was earned. What is happening is "I need..I'll be back tomorrow to move your desk" (just an example) and I don't see them till they need something else and it's the same thing to where I've given 3 times and have still heared the "I'll be by tomorrow " speech. 
I have locked my door and I think it's a better way of helping because instead of getting sick of hearing excuses, from now on it will be "business is business". You bring me what you have offered and I will give you what you need, or just straight out ask for it, no promises or returned favors.
It still irritates me the "business is business " saying but it's less stressful on me and I can help out others that I see actually will benefit.
As a little girl I would ask my father to loan me a $20 for example and he would laugh and say why do you ask me to loan you something I don't expect back my princess?, we would laugh then I would say father may I have.. and he would smile and give.. and we would laugh together. We kept that going forever, it was our thing, our joke.
I learned from that and when my offsprings would ask for a loan and say they would pay it back I would tell them no, you use it for something else you might need later on.
I will help if someone is in need without expectation so just except it and do what you have to do to fix your situation.
I'm not a business person, I write and I try to live stress free.

Stay Wicked.
