Lovely loving sisters

What does a sister mean?

A sister means someone you quarrel with so a lot
but miss when the other is not home

A sister is someone you compete with
in taking their mom's heart and love

A sister means someone who easily shouts at you
but that you easily forgive

A sister is someone you first seek
when you do not find someone
on your arriving home

A sister is someone you will always love
in spite of differences, jealousy and quarrels
