Wowwwwww, i must admit i admire your family it's so beautiful and lovely. Your mum, i admire her social ways and from what i see here she's someone very open and you may be free to tell her everything and not forgetting she's a true definition of making your mum your best friend.
I love the family bond for families are blessings from God and you belonging to such a wonderful one you need to thank God everyday for it.
