Buy baby sleeping bags for me

When you are asking someone a favor you have to be aware of the fact that this person might ask you for the same thing one day. Are you aware of that? When he or she has done something for you it is natural that he or she might ask you for the same thing and you will have no option but to do it. I believe that there is plenty of people out there who are not aware of that and they are using others too often for their own needs. That is something that you should avoid in my opinion. My mother can^t understand it obviously and she wants something from me almost every day. Yesterday, for example, she has called me and told me to buy her baby sleeping bags because she needs them for some reason and she doesn^t have time to go buy them on her own. First of all I don^t believe in the fact that she doesn^t have enough time to do it. That is really strange for me and I can^t believe in it. The other thing is that I don^t understand why I should be doing shopping for her. She might as well buy those baby sleeping bags on her own. It is up to her when she is going to find the time to do that. I wonder whether she would find the time to do the same for me. Let me know what do you think about all of this.
