Nothing is free
This is obvious, everything will cost you something, even any kind action might cost you thing. So if you have no cash better never and ever take anything from stranger even though you may need a help for some direction.

My wife and I went to a popular market in the town of one country then suddenly one little girl gave me 3 flowers and said it is free well, of course I spontaneously grabbed them then the girl asked some money and I did not have that much, so the girl quickly just toke my coin and asked me to return the 2 flowers, unbelievable.
The other event was still in the same place one young man approached us started to give bless bound my wrist with colorful bracelet since I was experience enough so I refused unfortunately it was too late, I should have ignored at the very first time they greeted me, I could not say no as everybody else seemed his friends staring at me fiercely so I asked how much he just said up to you but since I did not have smaller note so I dared ask for change luckily he agreed to return me some money however it was really painful.

Last one we were in the train station where the system was a bit confusing to me and not in English, I looked desperate and one lady middle aged offered help just guided me along how to buy train ticket from the machine well I believed it was common help every body should do, but guess what ? she asked me some buck. Damn !!! what the fish,, three times only in my one trip I should suffer this much.

I mean I would be fine if you beg and I donate or they should tell me up front the help will be chargeable, but hold on a second ! That is right, nothing is free. We must try to help as many as people we can within our capability but do remember one thing not everybody will agree, in fact these experience thought me a precious lesson when I am travelling do not easily believe in stranger help. One thing for sure nothing is free.
