Elma, Czechs are not raised to offend people.In the case of this man...I think he doesn't want to neither ignore you nor decline you...he wants to play with you as soon as he finish one of his games and then he can accept your invitation. This is what I think is going on. People do that sometimes to me...they kind of put me into waiting line...well, that's ok with me...if I do not want to wait...I just cancel invitation. Do not put him into your enemies, please...he is a good man...better...write him letter that it upsets you.I think he is not aware of you being offended right now.
