Is it normal to cry?

I cried today with my dad as I told him goodbye as he’s leaving to Mexico for a mini trip.

i wanted force myslef to not cry like I usually do but this time I wouldn’t hold it on and cried while hugging him. I never have cried in my entire life even tho I live Alone and see dad often just saying the word goodbye made me burst into tears.

Is it normal to cry?
