There are those little things that are somewhat in the form of portraying 'I Love You' without actually saying it.
1. Family Parties
Even though they're waiting for the clock to move faster, they accompany you to those loud and often embarrassing family gatherings. They could be talking to that certain relative that doesn't stop gossiping with that extremely strong coffee breath but they are all smiles and always respectful of each relative. Even though deep down they are dying out there they are more than willing to sacrifice whatever plans to accompany you to whatever just because they love you.
Not exactly talking about sexual or creepy way of touching. More like that time you're behind that kitchen sink or cooking and they come and wrap their arms around you, the simplest kiss on the cheek or forehead at anytime and when you're driving and they grab your hand and hold it.
This one could be annoying to some people but personally to me, it shows how much they care. The concerns when you haven't communicated about reaching a certain destination, when they tell you to drive safe every time before you leave just those common little worries that we all sometimes get.
Making sure you know that you're loved is something beautiful.
Of course there is many other little things, comment some down below if you've noticed or gone through some also!
