Is it important for your friends to remember your birthday for you? We have good acquaintances, a married couple (they are 24-25 years old), with them we always find common ground. The husband always helps them when their animals get sick, gives recommendations on treatment, as he is a vet. In general, we supported them during a difficult period of life. Communication mostly in person, rarely do we exchange messages. So, we've been communicating with them for three years now, and they forget about our anniversary every time (they are close to us). The first year they congratulated us because we invited them to celebrate. And on their birthday, we always congratulate them, while they always invite us to celebrate, sit down.
