A coworker and I are both getting married this year. We like each other but aren't very close. Neither of us invited the other to our respective weddings, but we did invite other coworkers that we are closer to in our office. Another coworker is arranging a surprise bridal shower for my coworker getting married (her wedding is happening before mine) and it has been implied that we should buy presents off their registry.
There's a part of me that knows I'd look like a jerk if I didn't get them something, but on the other hand I don't feel really eager to buy this person a gift to a wedding in which I know I wasn't invited but other coworkers were.
I also don't want my coworkers to throw me a wedding shower (if they even do, who knows?) for the same reason: I don't want people that weren't invited to feel obligated to buy something off the registry. It just feels weird and awkward.
Thoughts and suggestions on how to deal with this?
