Just found out that my sisters just booked two weeks holiday whereby one of them clashes when we were about to book a trip Egypt for OH big birthday.
We have children and therefore don't like DD having time off school, sister doesn't and therefore can go anytime of the year. She's already booked two mini breaks so far this year.
We can't go in the summer holidays due to OH work commitments (works in industry where summer is busy) and now the extra amount it would cost if we could.
We have saved up for two years to afford this holiday and now can't go especially with our elderly dad who sister lives closer to and pops in on her way home every night now needing to come to us whilst she is away because they are slowly getting worse and need help and checking in on daily.
Am I being extremely unreasonable to be extremely annoyed and upset with sister?
