Only thing I wish hadn't happened was my wife's Aunt throwing a hissy fit after the wedding because I did not go out of my way to thank them for their "generous" gift during my speech. Seemingly I made the mistake (as far as she was concerned) of just giving a general thank you and sending out cards later. I wouldn't mind but it was only €150 anyway
Aside from that, absolutely perfect day and 2nd best day of my life, all in Ireland with all the family there
