Was that a reaction of them being surprised, shy and/or flustered?
Is this a shy girl reaction?
Context:
I've known this girl for 2 years. We don't see each other that much during the months (it's like 5 or 6 minutes and it's like twice per week).
Whenever I tell them something that's like a compliment for them, they seem to get shocked, surprised and laugh a little (more like a giggle).
It kind of goes like the following:
Me: Hey
Her: Hey
Me: How are you?
Her: Good and you?
Me: Good
Her: Good to know
Me:Nice, have you seen *mentions about the series*
Her: Oh yeah, *mentions about the series*
After that little conversation ends
Me: Hey, did you started to take modeling photo sessions?
Her: OMG, *giggles* (or makes a little laugh). *stays a little speechless*. Byeeee
Then she leaves
The following day, we keep on talking like we usually do.
