A friend and I and our respective tweens, due to our interest in practical projects for application of Artificial Intelligence for our tweens, were in touch with a few mentors for past few months. We were working out the feasibility of a few ideas. When we were almost on the verge of finalizing a project for our kids, my friend tells me that her child cannot spare time for this as they are preoccupied with another project. They are a part of a team that is based abroad and are working online. They will be traveling abroad in March for some expo in that regard. The project they are working on is in the same field that we were discussing about. I was spellbound. I didn’t know what to make out of this. I kept quiet. Then for some days she did not call me at all. (I did not call too. I was hurt. Moreover, it was always she who would call me at least twice a day). She called a common friend a few days later and asked her to convince me to understand her. It seems she told the common friend that since she (my friend) has lost her husband and since she’s a single parent and sole bread winner, she had to grab the opportunity of joining the online team. There was room for my child in the team but she thought it would be better if only her child joins. I don’t know her reasoning behind this. I called her once last week on her child’s birthday to wish. I spoke briefly but did not rake up the topic. Today, I received a call from my child's school informing me that my friend's child will be a part of the school team that my child is a part of. This team will represent the school in some Math competition. The teacher called me to ask if it's Ok with me if my child stays back after school to assist my friend's child to prepare for the competition. I said Ok. The teacher (She is not aware of the personal relation between me and my friend. she only knows us as 2 mothers whose kids are in the same school) thanked me and added that it's kind of me to allow my child to help others especially those who have lost an important family member. I didn't know what to say. I am confused. I am hurt. I sympathize with my friend but I feel betrayed. i am sorry I feel like this. Am I self centered? Please guide me.
