You'll have to ask the one you challenged.
challenge declined
Could be nothing personal about it at all. A lot of times if I finish a game the previous opponent will offer a rematch. I will usually accept but maybe I already started another game, then I will decline since I can't play two at once. Or maybe I just need to go do something else. But it's nothing personal.
To declined a challenged should not be seriously taken as personal, because the person you are asking may have some important things to cope at.
Anotherbaap,
I usually decline if I cannot commit to a game because of family, personal or business commitments.
Or a time constraint in my current schedule due to social or other things, such as a tasty dinner being ready to eat or a hot date.


why?
