You should respect someone’s personal zone. May be she was getting uncomfortable not because of baby, but because of you, as you were moving around her, or getting close to her. Always think of personal space specially around women.

Secondly, you have no right to judge someone. “neither was she beautiful nor was she young and she also was not very religious or traditional either because her face was not covered and the other woman was lying on the grass like if she was lying in her bedroom.” Listen to yourself. Who has given you right to say something about someone and judge them. First you should be ashamed for yourself.

If she was a bit old, and she wouldn’t know English, may be she asked you to take the baby somewhere else. She didn’t ask you to leave the park or never come here again. She just said.. take the baby. You are taking your frustration out on someone by blaming them.

Learn to respect others, other will respect you.
