Everyone has a unique, God-given way of telling you they care, but I really like the five love languages for a general rule.
Quality time (spending time with someone)
Acts of service (doing things for someone)
Gift giving
Physical touch
Words of commendation/praise
They say everyone has a primary and secondary love language. (example: my primary love language is acts of service, and the secondary is likely quality time, which means that when I want to do something really nice for someone, I'll do one of those; and in return, that is what makes me feel the most special from someone else
). Like I said before, everyone is unique; I've always thought it was kinda fun to observe myself and others and see what blend of the love languages they have, everyone is a bit different
