15 years of friendship...
does that worth more than $800 + 2 days off work when i'm suppose to be at the busiest time in my phd (although i can easily make up for that on weekends) + not able to spend more days holiday overseas while going for a conference (well actually only involves 2 days difference)

a friend who have been my classmate for more than 6 years, a friend whom i've known for more than half of my life,
is getting married in jan next year.
is it worth my effort time and money to fly back just to attend her wedding?!
we don't belong in the same 'group' of close friends but she's one of the friends whom i'm still in touch with since we finished high school.
it's more of the 'quantity' than 'quality' when it comes to describing how close we actully are. we've known each other for so many years but we're not each other's best buddies.
it's a tough call!!
