I am eldest of three sisters. No drip feed,I have always been the problem solver and literally support human being for the other two. Middle sister A is on work visa, youngest B is on graduate visa,expiring next feb, her current job ends on August. Most probably she will have to leave UK as there's no hope on hell that she will secure a sponsored job with 38k salary.A is pretty upset about this so we thought let's go on a trip to Spain as B hasn't been to Europe at all, to have something to remember etc. Now I had booked easyjet holiday on feb 29th, flight is next Wednesday. Guess when B applied for schengen visa? May 19th. A has applied 1st week of May and got her visa last week.We are both freaking out and there's no response from B. She is a procrastinating champion and pretty sure herself that she got ADHD. First it was weeks of oh there's no visa appointments, then it was oh when I get one online I can't complete as I didn't have all.my paperwork...all the while she knew from reddit forum exactly what was happening at BLS processing center. The whole point of this holiday was to go as 3 sisters .Sister A is going to moan if just two of us go on the trip, and how are we going to recover B's portion of the cost? A and B has joint travel insurance but I don't think this situation is covered. A might say oh B is lower earner so lets absorb the cost .A had already proposed that we cover her spending money once we are there.AIBU to tell B that I don't want to be out of pocket due to her lazyness and tell A to accept we can't subsidise another adult?
