Do you share your food packages while in group/while travelling

No. It's dangerous. It's even written in railways stn and trains 'Do not accept food from strangers.'

I accept sometimes too. But only if we've been in company for a day or night or so. If i feel suspicious, i refuse. But i love sharing food stuff in trains (or for that matter anywhere). It's because it gives a good feeling. I especially love giving little things to the kids in my compartment. I guess why most of us share is because we might not meet again and trains and the kind are the only places where you can make momentary friends!
