Henry and Isabel were recently married and had a news to tell their parents- Isabel was pregnant! On Friday, the night before telling their parents, they reflected on all of the experiences they've had in their relationship up to this point and how crazy the life was, and now they'd have to do a lot of researches to get ready for raising a baby. They didn't have any experiences, so they were hoping they'd receive support from their parents.
Saturday came and both sets of parents arrived for dinner. Isabel had made a spaghetti, and afterwards they had some ice-creams. Mario, Isabel's dad, didn't go for ice-cream as he wanted to reduce the amount of sugar in his diet. Catherine, Henry's mum, started yawning. She was tired because she had many work earlier that morning.
After dinner, they all gathered by the fire as it was winter. There was still lots of snow outside. Maria, Isabel's mum, mentioned that she had wonderful memory of playing in the snow when she was a little girl. She had many winter clothes and loved wearing them when it was snowing in all the natures.
After they had warmed up, Henry and Isabel were ready to tell them the exciting news. "Guys, Isabel's pregnant!" Both sets of parents jumped for joy! "I've waited many times for this moment", said Catherine. They talked for hours about how their lives would change. Isabel had been watching a lot of content online for first-time mothers, but the tips she got from her parents and parents-in-law were far more valuable. 11 o'clock came, and it was time to go. The parents giddily walked to their cars, excited for the little life that was on its way.
