Damn people

Today in or local target an older lady about 70ish came up and told me I was such a. Good big sister to look after my brother for my mom. Well I processed to say no that’s my son but thanks for telling me I look young enough to be his sister ( he’s 8 weeks old I’m 20) she then told me not to lie because pregnancy in young women isn’t expectable and that she needed to talk to my mom about me lying I then said lady no I’m 20 this is my son I conceived him and gave birth to him she then said no way possible ugh people
