My mother is interested in throwing a shower in my honor, and inviting her personal friends, neighbors, clients, and some of our family members. I live in PA, and she lives in NE. I wouldn't be able to travel back to my homestate for a shower, so she would like to throw this shower with my presence through Skype. My fiancee and I have 130 guests on our guest list, and I anticipate that NONE of the friends my mother would like to host at this shower will receive an actual invite to the wedding-- we just don't have the budget for it, and there is no such thing as a 'courtesy invite.' She, however, is a mother that lives far away from her daughter, and genuinely wants to do something special for me (which is very sweet). Will her friends and family (whose daughters have been supported by my mom's presence at their local weddings and/or showers) feel okay with this? Etiquette-wise, is this arrangement acceptable?
