what would you choose to do?

why didn't you invite your friend to go with you?If your friend also like to do,you can go together.i will ask my friend whether she has interest to go with me.Or she didn't want to go,i will solicit her opinion if i went there.If she is my truly friend and she know me,she will desire me to catch that special opprtunity.

Most of what you need to decide her revolves around the relationship you have with your friend. If they are truly your friend you should never ever stand them up. If the other event is something you really want to do then just tell your friend...sorry but something has come up that I really want to do and ask if you can postpone. You don't have to give an explanation but just be honest with them. If you really consider them a friend you owe it to them to consider them first. Of course if we are talking about love intrusts here the problem gets very complicated and you know it. Only you know the real answer to this. Never ever stand up a friend that you want to keep however.

Either way you end up wishing you were somewhere else. I never get into these situations because I hardly have anything exciting in my life. CheerS!!

i wouldnt stand my friend up but i would let them know of my special opportunity and organise another time to see them, especially if the special opportunity was a once of chance
