AIBU to not know what to give my son for a 21st birthday present? In my day we were given an expensive watch or piece of jewellery …. But times have changed and I do not have friends in a similar situation to discuss with them . So what does a 21st birthday present look like in 2021? ( and I know it depends on personal financial situations, and what people can afford, but I would just like to hear what other people do!)
