Been out of work since last april since bei g made redundant. xmas eve and a very old mate picked up on a facebook post and made me an offer. wasnt something i wanted to do and never saw myself doing, but he seems to think i'll be good at it and is prepared to take a risk. i said that i would feel happier if i went in for a couple of weeks and observed, for nothing, so we could both sus each other out.
then today i get a phone call offering me an interview for a job, of all the 200+ jobs i have have applied for this is the one that i wanted above all others. Now i feel bad about letting my mate down even tho we havent agreed anything.
How can i best approach this and let him know without stuffing it if i dont get the other job? I cant lie to him i need to come clean cos thats the type of guy i am!
