Lost my passport
At least it"s early enough for it to be no problem getting it replaced in time, not happy with all the extra cost though (including having to pay for an ESTA as you can"t just amend an existing one if you get a new passport number)
You should be glad you"re British, cos replacing it is just an administrative procedure, which you can repeat if necessary. I lost my Irish one a couple of years ago and received a strict letter about the seriousness of losing it and a statement that you can only ever have a lost passport replaced once in your life. I have found it so I must send to them to redeem my "one time" in case I need it in the future.
