Excuses or just being Lame??

Finally after months of preparation and waiting for the day to arrive, I am quite relieve it is over. I am talking about the wedding preparation and the dinner of my eldest son.  Never reliase there is so much preparation to be done and we would not be able to do it without the help of so many kind souls do assist us. Thank God, it did not put a big dent in our pockets as well. It was a good dinner and it went quite smoothly and I am so grateful for friends and relatives who had taken time off to attend the dinner.  Now I had time to reflect and think  what had transpire over the last few days. Perhaps it is time to evaluated some of the friendship. Despite invitation and enough notices were sent out very much earlier than the dinner date, not many bother about the rsvp part and some of the excuses I got for both the bachelor nite and the wedding dinner were not too convincing.
one response I got was I do not know your son. Since when do we need to know the couple when attending such function.As if knowing the person who invited you is not good enough reason??
Another one only told me he has to be at another friend's pre wedding shoot when I call to ask. what happen if I dont call at all , I will never know.Some were not feeling well. A courtesy call would have been appreciated. Another one was due to a flight delays and could not come back.A valid reason,but if proper planing this could have been avoided. I am not passing judgement just to express my disappointment. I remember when ever I had an appointement or invitation, I will ensure I do not enggage in other activities and if I do have on the same date or on the eve, I will ensure the activity will not tired me  lest I will not be able to make it on the day of the function. Also I will ensure it will be nearby so that I could not be delayed. However I am also happy to note some of my friends and that of my wife's took the trouble to attend the dinner even though they lived in far away(some from another country). One of my friend flew back from singapore after celebrating his mothers birthday in singapore. He left his wife in singapore to accompany the mother. such thoughtful persons.It is occasion like this we know who really value our friendship and who doe not.
