Background: I have a close group of friends that I have known for over 20 years (wow, typing that out makes me feel old!). One of the ladies (Diana) has been single for most of that time, while the rest of us have slowly been getting married and having children. In the past, Diana has expressed feeling a bit left out and lonely.
Well, 2 months from now, the only other single friend (Emily) is getting married. Diana is now officially the only single one left and I was worried about how she'd take Emily's wedding. However, Diana decided to plan a special day for Emily, and is really going out of her way to make it special for her.
The question: I was thinking that I'd like to plan a special birthday celebration for Diana. She hasn't had any special celebrations for herself. However, big birthday celebrations are not common in our circle. Would such a celebration come off as something nice to celebrate a friend, or as a pity party for the single girl?
