Quick Kiss!
OK, we know that T-shirt logic isn’t really a thing, but when you think about it, this means that for her boyfriend to ‘come back’ he would have had to have been there with her. Which means that he definitely knows she’s wearing this shirt… hmmm. It could be a situation of thinking his girlfriend was just super funny. Maybe she is. Or maybe it was her ploy all along to get him to think it’s ‘just a joke’… quick, no time to work it out, he’s coming back!
