If two people simultaneously do the same thing for each other, instead of each one doing it for himself, is that considered Gemilus chesed?
For example, if each of two people, need a chair to sit at the table, and they make an agreement between themselves that each one should carry a chair over to the table for the other person instead of each carrying a chair for himself, is this chesed?
It would seem that since one is not saving the other person any work at all, since he has to do the same thing for his friend he gained nothing form what his friend did for him, so where's the chessed.
On the other hand, the bottom line is that right now each has a chair due to the other person's work, and If the other had not done it he would have to have done it for himself, so each did a chessed for the other, regardless of the fact that his friend also did it?
[Note: I understand that there might be an advantage in doing things this way, in order to get oneself used to doing things for others. If one does something for someone even when he doesn't need him to, it will strengthen his character and positive relationship to others. But my question is, is this just an exercise in chesed character training, or is it actually considered a mitzvah of chessed?]
