This has happened to me a few times recently and just wanted to know if I'm over reacting !
Some good friends recently had birthdays (including 50ths), and on separate occasions.
I went to effort choosing the gifts for them, knowing they were special and bespoke to that friend. Met them for dinner but none of my friend made an effort to open the present when I gave it to them. At the end of dinner the first time, I said excitedly 'Aren't you going to open the present then?' And she said something about was going to take it home but then ended up opening it. I just wanted to see her face and talk about the present, not just be thanked over text.
Then it happened a couple of times again . I'd chosen some nice gifts which just sat on the table unopened all night and I couldn't be bothered to ask her to open jt . It wasn't like a big birthday do.. it was just 2 couples. Of course I got a thank you text later but I felt deflated to be honest as I'd wanted to chat about the present . It just led me to wonder, Is it the done thing not to open presents when they're given to you? (it was either their actual birthday or the day was in the past so it's not like they were saving it to open on the birthday).
