Today I have read through this article about how difficult is invalids’ life.

It is just severe so to act like that. It’s ok when healthy people pay money for the goods or services - they always have a choice. I, for example, never drive on free-of-charge roads and do not buy cheap products. But to rook invalids in such way is improbably impudently. They do not have choice unless absolutely to cancel a trip.

There is not enough kindness and care to feeble in our world.

Probably for these people money is the most important thing in the world!
