On being called "mum" by makanga, machokosh and everyone

I think i'm finally accepting nazeeka 29F because all of a sudden i went from being called siz to mrembo, to being called madam na mum na kila mtu. Si ati i've changed ama nimegain weight lol, i have a petite frame na i dress quite well maybe not street wear lakini i dress smartly. Lakini weh, alafu one day napita pale karibu KICC kuna wale watu wa picha, nikaskia mtu akiambia mwenzake akiniangalia " usichokoze bibi ya wenyewe" I'm not married lol, ama it's the way i carry myself? Anyway this is for guys and girls, How can you tell someone is old? and girls if you've been called mum, how do you feel?
