Ok, this is coming from the Mother of a GIRL, and from our point of biew prom is a HUGE expense for us, and much less for the boy. That being said, I would NEVER allow another parent to be held up with their plans the way this parent is holding you and your son up. Also, your expenses are costly as well, with the tux rental, tickets, and time lost from work to be fitted and to go to the rpom as well. (My comment about the cost being much more for the girl is just my own point of view because we have done this so many times and the dresses have to be purchased, not rented, and are so darn expensive) Honestly, less expensive dresses can be bought but we have opted for her senior prom to go "all out", but I still would NEVER make my daughter's boyfriend wait the way your son has been made to wait until the last minute to make his plans. I would ask the girl's parents for a material swatch from her dress (I assume that she bought her dress already) and just make your appt to go orent the tux without her. My daughter gave her boyfriend one of the swatches that her dress came with, (there were 3) and he took it to match to his tux vest and tie, and I used one to order hif buttoneer as well. (sorry if I spelled that wrong) I ordered his flowers for my daughter since she was so busy with school, work, and rehersals for her school plays etc. He did his own thiing getting her corsage. If for some reason your son's girlfriend is not allowed to go to prom, which I doubt will happen, then have him go with his friends anyway. Trust me, he will still have a blast. Many of the kids these days go without dates. They all have a blast. I am so sorry that they are making this more stressful for you and your son. I would speak to the parents directly, and just explain the work schedule and all of the reasons that you explained here. Also tell them that you totally understand their thinking about the deal with her not going to prom as a punishment, but that your son will be going either way. He has done all that you had requested of him, so he should not be punished. Hope he has a blast!
