When I use to work and income, I generally gave all expenses of food and transport of them, who travels with me (to shop or other places). Because I knew, I am incoming money so I should take care of that. Now I don’t have that much income, and what happening now, others doesn’t care whether I can bare all expenses or not. They order for food and other thing, don’t care, weather I need anything or my son.
No worry, life is a big teacher, every moment it will teach you something, which always happens, but you didn’t noticed.
